通过对 Gd及不同配比的 Gd- Dy合金的 X射线衍射分析和磁热效应 T- Δ Tad曲线测量结果的分析表明 ,Dy的添加没有改变 Gd的晶体结构 ,而使其居里温度和磁热效应发生有规律的改变。
The results of X-ray diffraction analysis and T-ΔTad curve measurement of Gd and different proportions of Gd-Dy alloy show that the addition of Dy does not change the crystal structure of Gd, and the Curie temperature and magnetocaloric effect There are regular changes.
