Circular Magnetization Processes In CoFeNi Electroplated Wires

摘要

Circular magnetization processes in electroplated wires is an important topic having straight connection with sensor applications of these soft magnetic materials. In present work the longitudinal and circular hysteresis loops were measured and corre sponding magnetization processes were studied in Cu_(98)Be_2/Co_16Fe_(20)Ni_(64) wires. The longitudinal hysteresis loops, M_z-H_z, were measured by inductive technique in a frequency range of 10 to 70 Hz. The circular magnetization curves (M_ψ- H_ψ) were measured for frequencies of 50 and 100 kHz in the H9 field up to 1500A/m for different values of the axial external field of 0 to 500 A/m. The longitudinal and circular magnetization curves are comparatively analyzed.
