摘要：

The critical exponent behavior of LaCr0.3Mn0.7O3 compound in the vicinity of ferromagnetic transition was studied by measuring isothermal dc magnetization and by analyzing them in terms of modified Arrott plot method. The critical exponents beta, gamma and delta corresponding to the spontaneous magnetization, initial magnetic susceptibility and isothermal magnetization with T-C=186 K were determined to be 0.325 +/- 0.006, 1.247 +/- 0.066 and 4.823 +/- 0.004 respectively and are found to be comparable to the values predicted by 3D Ising model. The obtained result is discussed in terms of presence of strong magnetic anisotropy. (C) 2016 Elsevier B.V. All rights reserved.
