Synthesis and Characterization of Divalent and Trivalent Ions Substituted W-type Hexagonal Ferrites for High Frequency Applications

Abstract

In recent times, there came a huge surge of interest in the field of magnetism, and research in this field has not been that much livelier than it is today. This renewed interest came mainly from three major advancements; firstly, development of completely new class of magnetic materials known as ferrites, secondly, the concept of neutron diffraction to visualize the magnetic moment of individual atoms and lastly, the evolution of computer where magnetic devices found a lot of significance [1]. Magnetic materials are usually categorized on the basis of atomic structure of the respective materials along with magnitude and sign of susceptibility as shown in Figure
