Available in PDF, EPUB and Kindle. Book excerpt: A new method has been developed for studying the galvanomagnetic as well as the magnetic properties of ferromagnetic materials. The method has been applied to thin films of nickel and permalloy and has yielded results for the conductivity, magnetoresistance anisotropy, extraordinary Hall coefficient, saturation magnetization, and magnetic relaxation time in these materials at microwave frequencies. The new method consists of measuring the second harmonic signal generated by galvanomagnetic interactions when an electromagnetic wave is incident on a magnetized conducting ferromagnetic film. In a ferromagnetic material, the relationship between current density and the applied electric fields takes the usual form of Ohm's Law with second and third termis due to galvanomagnetic effects. The measurement of the microwave galvanomagnetic properties of ferromagnetic materials by the second harmonic method has an advantage over the measurement of the dc signal in that two measurements can be made - the magnitude and phase of the galvanomagnetically-induced signal. The process of extracting the material parameters from the measured data is thus greatly simplified. In addition, the method has been shown to be a sensitive probe of the state of magnetization in thin films. It can be extended to study in greater detail films with spacial variations in magnetization, as in standing spin waves, non-linearities in the magnetization at high powers, as well as galvanomagnetic effects in magnetic semiconductors or paramagnetics.

This book was released on 2013-11-21 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, interest in the field of interaction of microwaves with ferrimagnetics has steadily increased. Investigations in tlris field have led to the development of a number of devices used for a variety of applications. The initial emphasis of the investigators was on the microwave behavior of ferrimagnetics placed in cavities and metallic waveguides and associated devices. This work has been presented in various books, monographs, and reviews written during the sixties. In recent years, interest in microwave propagation in ferrimagnetics has shifted from loaded waveguides to relatively new areas, e. g. , magnetostatic and magnetoelastic waves in layered structures, microwave propagation in ferrimagnetic strip lines and microstrips, etc. Such investigations are important from the viewpoint of devices such as delay lines, filters, convolvers, guided wave amplifiers, striplines, and microstrip phase shif ters, circulators, edge guided mode isolators, etc. As such, we feit the need for a text (meant for graduate students starting work in these areas as weil as practicing electrical engineers and applied physicists) which presents a coherent account of the various aspects of propagation of microwaves (electromagnetic as weil as magnetoelastic) in biased ferrimagnetics and discusses the relatively recent developments in the theory and operation of the aforementioned devices, and this book is the result. A biased ferrimagnetic is, in the mathematical sense, a complicated medium, electromagnetically as weil as elastically.
