Strain induced magnetic domain evolution and spin re-orientation transition in epitaxial manganite films

Abstract

The evolution of magnetic domain structure in epitaxial La${}_{0.625}$Ca${}_{0.375}$MnO${}_3$ films on (001) NdGaO${}_3$ is monitored as a function of temperature and magnetic field using Magnetic Force Microscopy. We see two distinct regions of magnetic orientational order; one in-plane displaying contrast-less image and the other tilted away from the film plane forming a distinct stripe pattern. A strong domain splitting is observed at the boundary of two regions, which is resilient to reorientation with temperature and magnetic field. We propose a model magnetic free energy functional to explain the mechanism of domain splitting seen in manganite films.
