摘要: Abstract The structural and magnetic properties of Mg x Co 1− FeCrO 4 ( =0.0, 0.1, 0.2, 0.3, 0.4, 0.5 0.6) system have been investigated by X-ray diffraction, magnetization, AC susceptibility Mossbauer spectroscopy techniques. Magnetization measurements exhibit Neel's collinear ferrimagnetic structure for the range studied, which is further supported variation Neel temperature with Mg-content. temperatures calculated theoretically are in agreement those deduced experimentally from measurements. results suggest existence two types spin–spin relaxation, smaller clusters relaxing at a faster rate as compared to larger ones giving rise quadrupole doublet
