3D-Ising like ferromagnetism in skyrmionic-bubbles host infinite-layer La0.825Sr0.175MnO3 manganite perovskite

Abstract

The critical behavior of infinite-layer La0.825Sr0.175MnO3 of Ruddlesden–Popper series manganite has been studied around the transition temperature (). To reveal the universality class that explains the critical behavior in La0.825Sr0.175MnO3 several methods, such as modified Arrott plots, Kouvel–Fisher, entropy and critical isotherm analysis have been employed. The critical exponent for infinite-layer is obtained independently from critical magnetization isotherm and found to satisfy the Widom scaling relation . The universality class of the critical phenomenon in infinite-layer La0.825Sr0.175MnO3 manganite can be explained with the help of renormalization group theory approach for three dimensional (3D) systems. We have shown that a short-range 3D-Ising type interaction is responsible for ferromagnetic and second-order phase transition to paramagnetic phase.
