Magnetocrystalline Anisotropy, Magnetostriction and Permeability of MnZnFe Ternary Ferrite Single Crystals III. Temperature Dependence

Although progress has been made in clarifying the details of magnetization processes in MnZnFe ternary ferrite single crystals at room temperature, little is known of the temperature dependences of crystal properties. The changes with temperature (liquid nitrogen to 300 K) in magnetostriction in the ≪100≫ and ≪111≫ directions, in the initial permeability, and in the magnetic anisotropy constants K

and K

. Contrary to expectations, however, the value of K
1
was not the only factor related to the initial permeability maximum, and a simple explanation of the temperature characteristics in terms of anisotropy alone is not possible.
