制备了NixFe 1-xCr 2 O 4、CuxNi 1-xCr 2 O 4和CuxCo 1-xCr 2 O 4系统，并研究了它们的晶体学性质。考虑到Jahn-Teller效应，表明A位Cu 2+比A位Fe 2+更有效地稳定四氢呋喃（c/a 1至c/a<1）。
The systems NixFe1−xCr2O4, CuxNi1−xCr2O4, and CuxCo1−xCr2O4 have been prepared and their crystallographic properties studied. From consideration of Jahn‐Teller effects, it was shown that A‐site Cu2+ is more effective than A‐site Fe2+ in stabilizing a tetragonal (c/a 1 to c/a<1.
