Abstract

We present a study of the annealing effect and its influence on magnetic and structural properties for a series of Heusler alloys Ni50-xCoxMn35.5In14.5 (x=0,3,5) prepared in ribbon form. We studied the morphology and composition using scanning electron microscopy (SEM) equipped with an X-ray microanalyzer (EDX). The magnetic properties were determined by two methods: electron magnetic resonance (EMR) and vibrating sample magetometer (VSM). We found that cobalt content in the annealed samples reveals an additional magnetic phase transition at lower temperatures.

摘要

我们展示了一项关于一系列带状制备的赫斯勒合金Ni50-xCoxMn35.5In14.5（x = 0,3,5）的退火效应及其对磁性和结构性能影响的研究。我们使用配备X射线微分析仪（EDX）的扫描电子显微镜（SEM）研究了其形态和成分。通过两种方法测定磁性：电子磁共振（EMR）和振动样品磁强计（VSM）。我们发现，退火样品中的钴含量在较低温度下显示出额外的磁相变。
