Abstract
Abstract Magnetic ordering and critical exponents of Pr0.6Sr0.35Ag0.05MnO3 (x = 0.05) and Pr0.6Sr0.3Ag0.1MnO3 (x = 0.1) ceramics are identified by magnetic measurements. Banerjee criterion and field dependences of the ΔSMmax disclose that both samples exhibit a second-order phase transition. The values obtained for the magnetic performances make these samples promising candidates for magnetic refrigeration. The determined exponents obey the mean-field model with a long-range ferromagnetic interaction. The reliability of the obtained critical exponents is examined by using the universal scaling hypothesis. Temperature variation in effective exponents βeff and γeff resemble with those for disordered ferromagnet. Using critical exponents universal curves for the ΔSM(T) are constructed.
