Abstract

The modified Arrott plots and Kouvel-Fisher analysis are used to investigate the critical behavior of CrTe_1-xSb_x ferromagnetic material near its transition temperature Tc. The Ferro-Paramagnetic transition is found to be a second-order phase transition. For x=0.2, the critical exponents closely follow the Mean Field Model with the estimated values of the exponents: β=0.60±0.03, γ=1.00±0.03 and δ=2.67±0.03. We also found with increasing Sb-concentrations, the critical exponents significantly deviate from the mean field values and gradually shift towards the 3-Dimensional behavior. The deviation may indicate changes in the spin configuration with increasing Sb concentrations.
