X-ray diffraction study of the CuCr2O4-NiFe2O4 system
Phase relations in the Cu1-xNixCr2(1-x) solid-solution system, containing Jahn-Teller active cations, were studied by powder x-ray diffraction. The solid solutions with jc > 0.5 were found to have a cubic NiFe2O4(Fd3m) structure. In the range 0.1
