Influences of Ni-doping on critical behaviors of La0. 7Sr0. 3Mn1− xNixO3
We have studied the critical behaviors of rhombohedral La0. 7Sr0. 3Mn1− xNixO3 (x= 0.01,
0.02 and 0.03) manganites by analyzing isothermal magnetization data recorded at
temperatures around the ferromagnetic–paramagnetic phase transition (the Curie
temperature, TC). The experimental results reveal that all the samples undergo a second-
order phase transition. Using the modified Arrott plot method, the critical parameters
obtained are TC= 357.3 K, β= 0.394, γ= 1.092 and δ= 3.99 for x= 0.01; TC= 352.6 K, β …
