Investigation of the impact of A-site cation disorder on the structure, magnetic properties, and magnetic entropy change of trisubstituted divalent ions in La_0.7(Ba,Ca,Sr)_0.3MnO₃ manganite

Abstract

This study investigates the effect of A-site disorder, characterized by the average ionic radius ( < rA > ) and the cation mismatch (σ2), on the structural, magnetic, critical behavior,...
