Abstract
We have studied the critical behaviour in La0.5Sr0.5CoO3 near the paramagnetic-ferromagnetic transition temperature. We have analysed our dc magnetisation data near the transition temperature with the help of modified Arrott plots, Kouvel-Fisher method. We have determined the critical temperature Tc and the critical exponents, β and γ. With these 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.
