采用x射线衍射、磁测量、电子磁共振、反射光谱、x射线光电子能谱和二次离子质谱等方法研究了一系列含铜尖晶石固溶体（Mg1-xCuxAl2O4）的固态和表面性质。数据表明，溶液在体和表面之间是均匀的。在x= 0.1以下，铜离子主要占据八面体位，并且电子隔离。在x= 0.1以上，一半的Cu离子也占据了四面体的位置，并且电子离域的程度越来越大。
The solid state and surface properties of a series of copper containing spinel solid solutions (Mg1–xCuxAl2O4) have been studied using X-ray diffraction, magnetic measurements, e.p.r., reflectance spectroscopy, X-ray photoelectron spectroscopy and secondary ion mass spectrometry.The data indicate that the solutions are homogeneous as between the bulk and the surface. Below x= 0.1 the copper ions mainly occupy octahedral sites and are electronically isolated. Above x= 0.1 half the Cu ions also occupy tetrahedral sites and an increasing degree of electronic delocalisation occurs.
