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 Ba<sub>3</sub>Co<sub>2.4</sub>Ti<sub>0.4</sub>Fe<sub>23.2</sub>O<sub>41</sub> 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.
