The compounds Ni 1 -x Cux Cr2 04 (0 4~ x ~' 1 ) have been synthesised by solid-state reaction between basic nickel(II) carbonate, basic copper(II) carbonate and chromium (III) carbonate in required molar ratios at 800 ± 10°C for 20 hr. The reaction products have been characterized by chemical analyses and powder x-ray diffraction patterns. Magnetic susceptibility has been measured in the temperature range of 300-900 K at 10 kOe. All the products show ferrimagnetic behaviour with the ferrimagnetic Curie temperature (To) in the range of 50 -150 K. The curie temperature increases when copper(II) ion is substituted for nickel(II) ion in NiCr204. The experimental values of the average effective magneton number (~ agree with theoretical values.
