| dc.description | We have studied the critical behaviour in $La_{0.5}Sr_{0.5}CoO_{3}$ 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 $T_c$ and the critical exponents, $β$ and $γ$. With these values of $T_c$, $β$ and $γ$, we plot $M/(1-T/T_c)^β$ vs $H/(1-T/T_c)^γ$. All the data collapse on one of the two curves. This suggests that the data below and above $T_c$ obeys scaling, following a single equation of state. | |
