Abstract

In this paper, a gradual change in the hysteresis loop of Co-rich glass-coated microwire stress-annealed at variable temperature is observed. Such microwires annealed with a temperature gradient also present a variable squareness ratio and magnetic anisotropy field along the microwire's length. The obtained graded anisotropy has been attributed to a gradual modification of the domain structure along the microwire originated by a counterbalance between shape, magnetoelastic, and induced magnetic anisotropies. Accordingly, we propose a rather simple route to design graded magnetic anisotropy in a magnetic microwire.

摘要

在本文中，观察到在可变温度下进行应力退火的富钴玻璃包覆微丝的磁滞回线有逐渐变化。用温度梯度退火的此类微丝在其长度方向上也呈现出可变的矩形比和磁各向异性场。所获得的梯度各向异性归因于沿着微丝的畴结构的逐渐改变，这是由形状、磁致弹性和感应磁各向异性之间的平衡所引起的。因此，我们提出了一种相当简单的方法来设计磁性微丝中的梯度磁各向异性。
