The influence of temperature on Z-type hexagonal ferrite magnetic polymer material
The paper considers the result of low-frequency temperature measurements of magnetic polymeric composite material based on Ba3Co2.4Ti0.4Fe23.2O41 hexagonal ferrite. Hexagonal ferrite was sintered by the ceramic technology. The measurements were made by the measuring system, which consists from a precision LCR meter Agilent E4980A, a medium-format heat-cold chamber TNS 80 and a personal computer. It is shown that there is a nonlinear temperature dependence of the real part of magnetic permeability of experimental sample.
