Book excerpt: Our intent is to offer the reader an in-depth, systematic treatment of high-temperature superconducting material (HTS), superconducting quantum interference devices (SQUIDs) and their many applications. The book is organized into five chapters, the first being devoted to the applications of superconductors from macroscopic to microscopic, ranging from superconducting bulk, superconducting film, superconducting nanowire to Josephson junction. In second chapter, the present work attempts to review the various known types of weak links including the nano-wire, bi-epitaxial, bi-crystal, step-edge, and beam irradiation-based high-Tc Junctions. Chapter 3 is concerned with the basic theory and fabrication process for high-Tc YBCO nanoSQUID. Meanwhile, the issue of device degradation and 1/f noise are discussed. Subsequently, in Chapter 4, we review the development of two different types of YBCO magnetometers and high-Tc SQUID gradiometers. In conclusion, with the rapid development of quantum sensing, quantum communication and quantum computing, the Josephson junctions, the core elements of superconducting quantum circuits, are expected to more profound impact on our lives.

Available in PDF, EPUB and Kindle. Book excerpt: The behavior of high temperature superconducting quantum interference devices (SQUIDs) in the presence of high temperature superconducting surfaces has been investigated. When current sources are placed close to a superconducting imaging surface (SIS) an image current is produced due to the Meissner effect. When a SQUID magnetometer is placed near such a surface it will perform in a gradiometric fashion provided the SQUID and source distances to the SIS are much less than the size of the SIS. We present the first ever experimental verification of this effect for a high temperature SIS. Results are presented for two SQUID-SIS configurations, using a 100 mm diameter YBa2Cu3O{sub 7-{delta}} disc as the SIS. These results indicate that when the current source and sensor coil (SQUID) are close to the SIS, the behavior is that of a first-order gradiometer. The results are compared to analytic solutions as well as the theoretical predictions of a finite element model.

Available in PDF, EPUB and Kindle. Book excerpt: This book willbcof value to anyone who wishes to consider the use of SQUID-based magnetic sensing for anyone of a number of practical applications. The focus here is to examine in detail how SQUID technology is used and how. the results of the measurements obtained can be interpreted to provide useful information in a variety of real-world applications. The concentration is on those areas that have received the most attention, namely bioma~etism and nondestructive evaluation, but. the topics chosen include as well, geophysics, underwater ordnance detection, accelerometry and a few somewhat more exotic applications. To provide a reasonable perspective. an attempt has been made to consider competing technologies for most applications, and in some cases to consider how SQUID-based technology may be integrated with other technologies to provide an optimum total-system configuration. It is also the intention of the editor, that this book will be of major value to those scientists and engineers who will be required to build both the essential components and complete cryogenic SQUID systems which will be utilized in the various applications presented. Thus, there is a comprehensive review of the principles of SQUID operation, and a detailed exposition on the fabrication of high-temperature-superconducting (HTS) SQUIDs. Although the market is currently dominated by low-temperature superconducting (L TS) SQUIDs, it is reasonably certain that in the near future HTS SQUIDs will take over in most situations.

Available in PDF, EPUB and Kindle. Book excerpt: What Is High Temperature Superconductivity High-temperature superconductors are operatively defined as materials that behave as superconductors at temperatures above 77 K, the boiling point of liquid nitrogen, one of the simplest coolants in cryogenics. All materials currently known to conduct at ordinary pressures become superconducting at temperatures far below ambient, and therefore require cooling. The majority of high-temperature superconductors are ceramic materials. On the other hand, Metallic superconductors usually work below −200 °C: they are then called low-temperature superconductors. Metallic superconductors are also ordinary superconductors, since they were discovered and used before the high-temperature ones.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Localized detection of very small regularly placed magnetic systems, such as an array of tiny magnetic islands, has been of great interest to scientists for years because of their applications to data storage media. One such detection device, the micro-SQUID (microscopic superconducting quantum interference device), can be used to detect very small changes in magnetic flux. Most low Tc micro-SQUIDs (LTS) are made from aluminum or niobium. While an aluminum SQUID is relatively easy to fabricate, one often needs a low temperature system than can be cooled to 1K to see the critical current phenomenon. As a contrast, niobium which has a higher critical temperature, and a more complicated fabrication procedure due to its need to be fabricated in a extremely clean environment to achieve a reproducible value for its critical temperature, which is about 9.25 K. Such a SQUID will only need to be immersed in a helium bath for the superconducting transition to occur. Alternatives such as tin, indium and lead, which are soft superconductors, do not wet a silicon/silicon dioxide surface as easily as niobium and aluminum. However, the benefits of a successful implementation of these soft superconductors as SQUIDs could greatly outweigh their drawbacks in terms of reducing the amount of time necessary for fabrication and measurement as well as the low temperature system requirements. In this dissertation, the successful development of functional square and rectangular tin sub-microscopic SQUIDs for use as magnetometers is reported. The application of a germanium pre-nucleation layer, as a means of creating a electrically continuous path, offers an alternative to micro-SQUIDs fabricated under more involved methods as used in niobium SQUIDs. An image of the device surface showed that the roughness consisted of defects such as holes which gives rise to critical current fluctuations and vortex pinning due to magnetic hysteresis. However, the oscillations observed from several of these devices, were found to be smooth with sharp edges but with a diminished period of oscillation. Several devices were tested and their fabrication, measurement and characterization methods are described. Another important study incorporated in our analysis of these tin germanium SQUID included its reduction from the micrometer regime to its lowest functional geometry. Moreover, to avoid the operational breakdown of a SQUID due to magnetic hysteresis and a diminution in sensitivity, the condition 2IcL [less than or approximately equal to] 0 had to be satisfied, where Ic is the critical current and L is the inductance of the device and [Phi][subscript]0 is one flux quantum [Phi][subscript]0 = h /2e = 20.86 gauss [mu]m2. Experimental measurements showed that all of these devices had magnetic hysteresis and operated outside of this constraint. In addition, several devices exhibited extremely high critical currents when the temperature was lowered a few milli-Kelvin past the transition temperature. Furthermore, unstable regions were present in the minima of the modulations indicating that additional quantum effects were incorporated into the device as a result of screening currents and magnetic hysteresis behavior.
