Abstract
We have studied the critical behavior in La0.5Sr0.5CoO3 near the paramagnetic to ferromagnetic transition temperature. We have analyzed our dc magnetization data near the transition temperature with the help of the modified Arrot plot, Kouvel-Fisher method. We have determined the critical temperature Tc and the critical exponents β, γ, and δ. With the values of Tc, β, and γ, we plot M/(1−T/Tc)β vs H/(1−T/Tc)γ. All the data collapse on one of the two curves. This suggests that the data below and above Tc obeys scaling, following a single equation of state. The exponents are close to Heisenberg values.
