Abstract
Based on the modified Arrott plots and the critical isotherm analysis, the critical exponents of both La0.5Ca0.5MnO3 and La0.5Ca0.4Ag0.1MnO3 systems have been comprehensively studied and investigated near the paramagnetic-ferromagnetic (PM-FM) phase transition. Critical exponents, β, γ, and δ, which are corresponding to the thermal variation of the spontaneous magnetization, initial susceptibility, and the isothermal magnetization, respectively, obeyed the Widom scaling law δ = 1 + γ/β. It indicates thus the validity the obtained results. We performed then another analysis of the critical behavior via the magnetocaloric effect presenting an accord with the analysis of magnetization measurements. Relative cooling power (RCP) follows the evolution of the magnetic field as RCP ∼ H 1+1/δ . The acquired critical exponents were in conformity with those gotten from the modified Arrott plots and Widom scaling law.
