稀土-3d过渡金属化合物中稀土的X-射线磁性圆二色谱(XMCD)仍是一个研究课题。我们给出了ErFe2Laves相中Er的LiII和LiII边发生电四极跃迁的实验证据。将这些实验结果与考虑了晶体电场对Er格位影响的原子计算结果进行了比较。
X-ray Magnetic Circular Dichroism (XMCD) at LII,IIIedges of rare earths in rare earth–3d transition metal compounds is still a subject of study. We present experimental evidence of electric quadrupolar transitions at LIIIand LIIedges of Er in the ErFe2Laves phase. These experimental results are compared with atomic calculation taking into account crystal electric field effects on the Er site.
