Abstract

Ferrites, which are ceramic compounds or mixed crystals of different metallic oxides (Fe₂O₃) and are thought to be made up of cations occupying the spaces between oxygen ions in a close-packed structure. They are classified into two main types based on their magnetic properties: hard ferrites, that possesses high coercivity and soft ferrite, whose coercivity varies very low. They are classified into four different types according to their crystalline structure: spinel ferrites, garnet ferrites, hexaferrites, and orthoferrites. Each group represents a different manner in which atoms are arranged in the crystal lattice. Hexaferrite is a special class in which Y-type ferrites have the chemical formula Ba₂Me₂Fe₁₂O₂₂. In this formula, the symbol “Me” represents a metal ion with a + 2 charge. This can be zinc (Zn⁺²), nickel (Ni⁺²), cobalt (Co⁺²), or magnesium (Mg⁺²). Recent research has focused on containing various combinations of divalent and trivalent ions into Y-type hexaferrites, aiming to manipulate their crystal structure and enhance their electrical and magnetic properties, specifically targeting saturation magnetization and coercivity. Y-type ferrites are gaining importance in both scientific research and practical applications due to their exceptional dielectric loss characteristics and conductivity properties. These materials are increasingly utilized in various technological fields, including electromagnetic interference (EMI) shielding, microwave absorption, and applications in defense and aerospace industries. This study provides an in-depth examination of Y-type ferrites, exploring their synthesis methods, structural characteristics, and magnetic and dielectric properties.
