This book was released on 2011-08-05 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2010 in the subject Physics - Nuclear Physics, Dr. Babasaheb Ambedkar Marathwada University (-), course: PH.D., language: English, abstract: Wide scope is available to study these aspects of ferrite which at present to our knowledge was not probe by researchers. In relevance to the ever expanding possibilities, and potential that is available with the ferrite materials, the scope of presently undertaken work is designed carefully by selecting suitable ferrite and dopants. A sincere attempt was made to extract fruitful, exhaustive and, systematic information regarding structural, cation distribution, electrical, dielectric and magnetic aspects of the ferrite systems under investigations. In the present study, the properties of nickel ferrites substituted by diamagnetic Zn2+, non-magnetic trivalent In3+ ions and tetravalent Ce4+ ions are studied for various compositions. The properties are investigated with a view to understand the effect of divalent, trivalent and tetravalent substitution in nickel ferrite. The thesis consists of five chapters. Chapter 1 related to Scope, problem statement, theory of magnetism, ferrites, background, motivation and aim of the present work, properties of the samples under investigations, objective and outline of thesis. Chapter 2, 3 and 4 related to results and discussion of structural, electrical and magnetic properties of Ni1-xZnxFe2O4, NiInxFe2-xO4 and Ni1-2xCexFe2O4 ferrite system respectively. Chapter 5 gives the summary, discussion and conclusion on Zn, In and Ce substituted nickel ferrite. On summarizing the results obtained on Ni-Zn, Ni-In and Ni-Ce spinel ferrites it can be concluded that; • The structural properties are found to be varying in all the three systems. The lattice parameter of Ni ferrite systems increases with increasing valancy of dopants (Zn2+, In3+ and Ce4+). • The other prominent parameter of our structural study i.e. porosity reflects that with tetravalent substitution minimum porosity can be achieved. • The particle size does not show any significant difference in their values when substituted with Zn2+, In3+ and Ce4+. • The band frequency in IR spectra slightly changes with the substitution of Zn2+, In3+ and Ce4+. • The magnetic properties are very much affected as can be seen from the values of saturation magnetization of Zn2+, In3+ and Ce4+ substituted nickel ferrite.

This book was released on 2023-09-26 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferrites are ceramic, homogeneous materials composed of various oxides with iron oxide as their main constituent. Ferrites are a class of ceramic ferromagnetic materials that by definition can be magnetized to produce large magnetic flux densities in response to small applied magnetization forces. Further, ferrites are chemical compounds, ceramic with iron (III) oxide Fe2O3 as their principal components [1]. Ferrites are usually non-conductive ferrimagnetic ceramic compounds derived from iron oxides such as hematite (Fe2O3) or magnetite (Fe3O4) as well as oxides of other metals. Ferrites are, like most other ceramics, hard and brittle. Many of them are magnetic materials and they are used to make permanent magnets, ferrite cores for transformers and in various other applications.

Download or read book Hexaferrite Permanent Magnetic Materials written by Sami H. Mahmood and published by Materials Research Forum LLC. This book was released on 2016-10-10 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This concise book presents the basic concepts of magnetism and magnetic properties pertinent to permanent magnetic materials. Emphasis is placed on hexaferrite materials for permanent magnet applications, with M-type ferrites as the focal point. The relatively high metallicity of magnetic materials for practical applications imposes limitations for their efficient use. Accordingly, magnetic oxides with ferromagnetic properties emerged as the most widely used magnetic materials for practical applications, owing to their characteristic high resistivity and low eddy current losses, chemical stability, simplicity of production in mass quantities, and other favorable characteristics. An important class of these oxides is the class of hexagonal ferrites developed in the early 1950’s, which dominated the world market of permanent magnet applications since the end of the 1980’s. Among these ferrites, the magnetoplumbite (M-type) hexaferrite, is produced nowadays in large quantities at very competitive low prices, thus providing the permanent magnet market with probably the most cost-effective magnetic material.
