Sm~(3+) ions can substitute Cd atoms and occupy the lattice sites (center C).Sm~(3+) can also be located at the interstitial siteswith and without the next-nearest-neighbors of Cd vacancies,being called centers A and B,respectively.
Sm~(3+)可以取代Cd原子而位于晶格格点处(C中心),也可以处于晶格间隙位置依其次近邻是否存在Cd空位而分别构成A中心和B中心.
