Magnetic Properties of CoFeSiB/CoNi, CoFeSiB/FeNi, FeSiB/CoNi, FeSiB/FeNi Biphase Microwires in the Temperature Range 295-1200 K

摘要

We have studied the magnetic properties of two series of magnetically hiphase microwires with 1 mu m thickness of CoNi-based hard or FeNi-based soft shells with a core of FeSiS or FeCoSiS glass-coated microwires. The magnetic properties were analyzed as a function of temperature in the range from 295 K to 1200 K using a vibrating sample magnetometer. Analysis of the magnetization reversal of each phase with measuring temperature has been performed.
