Magnetic Order Suppression in Thin Film La<sub>1/3</sub>Sr<sub>2/3</sub>FeO<sub>3</sub>

POSTER

Abstract

Perovskites exhibit interesting emergent phenomena as a result of coupled spin, charge, and lattice degrees of freedom. These emergent phenomena are often accompanied by, or in competition with, charge- and spin-ordered states; La1/3Sr2/3FeO3 (LSFO) in particular exhibits a coupled paramagnetic-antiferromagnetic and charge disproportionation phase transition at ~190K that is well studied in thin films, bulk, and polycrystalline samples. This work observes new behavior in the magnetic order of thin film LSFO at low temperature. We have used various X-ray techniques to study the dissolution of the magnetic order and its character, and we present data-driven hypotheses on the nature of a newly formed competing phase. The results of this work will contribute to the understanding of strongly correlated magnetic ground-states in oxides in general.
