Abstract

The evolution of magnetic domain structure in epitaxial La0.625Ca0.375MnO3 films on (001) NdGaO3 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.
