Title: Observation of the structural phase transition in manganite films by magneto-optical imaging

Abstract

A high-resolution magneto-optical imaging technique is used to reveal the formation of twins occurring during a martensitic phase transition at {approx}105 K in La{sub 2/3}Ca{sub 1/3}MnO{sub 3} (LCMO) films grown on SrTiO{sub 3} (STO) substrates. The magnetic contrast arises due to the magneto-elastic tilts of the Mn- magnetic moments in the twins. Different magnetic structures are found in LCMO films grown on MgO, NGO, and LAO substrates showing the importance of the substrate material for the manganite film properties.
