Abstract

Results of obtaining and analyzing the temperature dependences of initial permeability of ferrite ceramics are presented in the paper. It was shown that the level of the defective state of ferrite ceramics can be obtained from the value of two parameters α and β of the phenomenological expression describing the experimental dependences. The results showed that the main criterion of the defect state is the parameter β/α, which is related to the elastic stresses in the material. An indicator of the structure perfection is also the value of the maximum of the initial permeability near the Curie temperature.
