Abstract

In DyPr–FeCo–B microwires with easy magnetization axis directed along the microwire axis, domains with radial magnetization are detected using magneto-optical indicator films. The width of radial domains decreases as the field increases to 30 mT and increases with the microwire diameter in the range of 60–105 μm. In wires of smaller diameter, the critical field of radial domain formation is lower. The effect of the periodic relief produced by scribing on the magnetization distribution perpendicular to the microwire is detected.

DyPr–FeCo–B微丝中的径向域

摘要

在具有易于沿着磁线轴指向的磁化轴的DyPr-FeCo-B微线中，使用磁光指示膜检测具有径向磁化的畴。径向磁畴的宽度随着磁场增加到30 mT而减小，并且随着微丝直径在60–105μm范围内而增大。在较小直径的导线中，径向畴形成的临界场较低。通过划线产生的周期性浮雕对垂直于微丝的磁化分布的影响被检测到。
