Abstract

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 corresponding magnetization processes were studied in Cu98Be2/Co16Fe20Ni64 wires. The longitudinal hysteresis loops, Mz-Hz, were measured by inductive technique in a frequency range of 10 to 70 Hz. The circular magnetization curves (Mφ- Hφ) were measured for frequencies of 50 and 100 kHz in the Hφ 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.

Highlights

  • Composite wires consisting of highly conductive cylindric central part and a ferromagnetic cover layer were actively studied in recent years [1,2,3,4]

  • Among them one could mention the dynamics of the domain wall displacement during the magnetization reversal or circular magnetization processes in bistable composite wires

  • By subtracting the sinusoidal voltage, one can get the peak of induced voltage associated with circular magnetization process VW = V2 – I · Rw (Fig.3), being Rw the resistance of the electroplated wire

Summary

Introduction

Composite wires consisting of highly conductive cylindric central part and a ferromagnetic cover layer were actively studied in recent years [1,2,3,4]. Among them one could mention the dynamics of the domain wall displacement during the magnetization reversal or circular magnetization processes in bistable composite wires. In electroplated wires the changes of this field over the thickness of the magnetic layer can be neglected. This simplification was used in a model description of giant magnetoimpedance in electroplated wires with high order magnetic anisotropy [8]. In this work the longitudinal and circular hysteresis loops were measured and corresponding magnetization processes were studied in Cu98Be2/Co16Fe20Ni64 wires
