Investigation of critical behavior of layered ferromagnetic Cr₂Te₃

High quality single crystal Cr₂Te₃ was synthesized by Chemical Vapor Transport (CVT) method.Single crystal XRD shows trigonal symmetry (P-31c). Critical behavior of ferromagnetic Cr₂Te₃was investigated by bulk isothermal magnetization around the ferromagnetic phase transition.From this data, we estimate modified Arrot plot, the Kouvel-Fisher plot, critical isotherm, Widom scaling and determine critical exponents β, γ, δ values & Curie temperature T_c=211.3K. After the scaling, the isothermal magnetization curves below and above the critical temperatures collapse into two independent universal branches which signifies the reliability of the critical exponent values estimation. The determined exponents match well with those calculated from the results of the renormalization group approach for a two-dimensional Ising system.
