Abstract The structural and magnetic properties of Y 1− x Gd x Fe 2 B y [ x = 0, 0.25, 0.5, 0.75 and 1; y = 0, 0.1, 0.15 and 0.2 for x = 0.25, 0.5, 0.75] have been investigated through X-ray diffraction and magnetization studies. The compounds with x = 0 and 1 are found to form in single phase with C15-type cubic Laves phase structure while those with x = 0.25, 0.5 and 0.75 are observed to form with small
摘要 Y 1− x Gd x Fe 2 B y [ x = 0, 0.25, 0.5, 0.75 and 1; y = 0, 0.1, 0.15 和 0.2 for x = 0.25, 0.5, 0.75] 已经通过 X 射线衍射和磁化研究进行了研究。发现 x = 0 和 1 的化合物以单相形式形成,具有 C15 型立方 Laves 相结构,而观察到 x = 0.25、0.5 和 0.75 的化合物与少量 RFe 3 相作为杂质相形成。化合物 Y 1− x Gd x Fe 2 B 0.2 [ x = 0.25, 0.5 和 0.75] 似乎在没有 RFe 3 相的情况下形成。由于硼在 Fe 位点的占据,晶格参数随着硼浓度的增加而降低。由于 B 的低位(与费米能级相比)2p 能级,发现随着硼的加入,磁化强度和居里温度变化不大。
