|Abstract: ||The present work deals with the detailed investigations on the magnetic properties of the mixed manganite system: NixCd1-xMn2O4 (0.2 less than or equal to x less than or equal to 0.8). In addition to Mn3+ anisotropy, the random substitution of diamagnetic ion at A-sites introduces further disorder in B-sites resulting in weakening of AB bonds. The results are compared with isotropic canted ferrites and reentrant systems. By applying ferromagnetic scaling law, successive transitions are identified as a function of temperature: paramagnetism to short-range order (or cluster state) to ferrimagnetism or canted magnetic state, depending on concentration range. The effect of random anisotropies gives rise to modified magnetic properties at low temperatures (T < 20 K) which mimic local canted state features, while spin-glass-like phase could exist at very low field and low temperature.|
