Dy对Gd磁热效应的影响

Influence of Dy on the Magnetocaloric Effect for Pure Metal Gd

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。

Comparison of the results of the X-ray diffraction patterns and the magnetocaloric effect T-ΔT ad curves for the samples of the pure metal Gd,Gd 0.9Dy 0.1,Gd 0.8Dy 0.2 and Gd 0.7Dy 0.3 indicates that the four specimens have the same crystal structure ,but different magnetocaloric properties.
