摘要:

本文报道了$R$ CoPO($R$ = La,Pr,Nd和Sm)的巡游铁磁相内的宽带电子自旋共振测量。我们发现,$R$取代是非常有效的逐步引入一个相当大的易平面磁晶各向异性内的Co子晶格。我们解释了我们的结果中的一个微妙的相互作用的结构效应和间接的相互作用之间的$f$和$d$轨道从$R$和钴,分别。

英文摘要:

We report on broad-band electron spin resonance measurements performed within the itinerant ferromagnetic phase of $R$CoPO ($R$ = La, Pr, Nd and Sm). We reveal that the $R$ substitution is highly effective in gradually introducing a sizeable easy-plane magnetocrystalline anisotropy within the Co sublattice. We explain our results in terms of a subtle interplay of structural effects and of indirect interactions between the $f$ and $d$ orbitals from $R$ and Co, respectively.
