چکیده انگلیسی
In this work, the magnetic properties and critical behavior around ferromagnetic-paramagnetic (FM-PM) phase transition in Ba1.7La0.3FeMoO6 compound have been investigated in detail. This compound exhibits a second-order magnetic phase transition with Curie temperature TC = 345 K. The critical exponents β, γ, and δ that are determined by using the modified Arrott plots (MAP), the Kouvel-Fisher (KF) and the critical isotherm analysis agree very well. Our results indicate a coexistence of short-range and long-range ferromagnetic (FM) interactions in Ba1.7La0.3FeMoO6 compound. The existence of long-range FM interactions in this compound can be associated with the crystal structure of materials with long-range Fe/Mo ordering parameter and strength of double-exchange interaction, whereas the existence of the short-range FM interactions can be explained by magnetic inhomogeneity and FM clusters.
