earth element) have perovskite and AuCu3 type structures, respectively. The binding energy of Sc 2p3/2 for ScBxRh3 increases with the boron concentration. The Knight shift of 45Sc observed by nuclear magnetic resonance spectroscopy decreases with increase of boron concentration. The decrement of the Knight shift corresponds the Sc 4s electron density at the Fermi level. The intensity ratio of f2: f1: f0
                                    ScBRh 3 -ScRh 3和CeBRh 3 -CeRh 3的固溶体通过电弧熔化法合成,其中R BRh 3和R Rh 3(R =稀土元素)分别具有
钙钛矿和AuCu 3型结构。ScB x Rh 3对Sc 2 p 3/2的结合能随
硼浓度的增加而增加。核磁共振波谱法观察到的45 Sc的奈特位移随
硼浓度的增加而降低。骑士换挡的减少对应于Sc 4费米能级的电子密度。Ce 3 d XPS光谱的f 2:  f 1:  f 0的强度比随CeB x Rh 3的
硼浓度而变化。可以得出结论,在ScB x Rh 3和CeB x Rh 3的两种情况下,A位原子上的电荷都随原子上未直接键合的B位原子上的浓度而变化。
