Temperature influence on the magnetic characteristics of Mn-Zn ferrite materials

Abstract

The subject of this paper was to investigate the temperature influence on the magnetic characteristics B-H of crystalline soft magnetic materials. Four different Mn-Zn ferrite material were investigated. The investigated ferrites were formed into ring-shaped cores with closed magnetic circuit and magnetizing and sensing windings were coiled on them. All cores were placed in the cryostat which was used to set temperature. Magnetic B-H characteristics was measured by computer controlled hysteresis graph. The results of the investigations were presented in the paper and analyzed. On the basis of presented results, the conclusions were formulated, which are also included in the paper.
