Abstract

The critical properties of perovskite manganite La0.67Pb0.33Mn1-xCOxO3 (0 ≤ x ≤ 0.08) around the paramagnetic-ferromagnetic phase transition are investigated through various techniques such as the modified Arrott plot, Kouvel-Fisher method and critical isotherm analysis. Though the nature of this transition was found to be in second order, the estimated critical exponents β (0.233 ≤ β ≤ 0.368), γ (1.03 ≤γ≤ 1.40) and δ (4.32 < δ ≤ 5.54) are in between the theoretically predicted values for three-dimensional Heisenberg and tricritical mean-field model. This model suggests the coexistence of the short-range and long-range ferromagnetic orders around the critical temperature. The values of the critical exponents obtained from different methods and the well-obeyed scaling behavior confirm that the calculated exponents are unambiguous and purely intrinsic to the system.
