Electronic and magnetic properties of epitaxial thin film of Nd\tsubscript{0.5}Ba\tsuscriptb{0.5}MnO\tsubscript{3}

Abstract

Contradictory reports about the electronic and magnetic behavior of bulk Nd0:5Ba0:5MnO3 with uniform disorder exist in the literature. In this work, we investigate the thin films of Nd0:5Ba0:5MnO3, grown by pulsed laser deposition. The success of epitaxial growth in a layer-by-layer mode and high quality of the films have been confirmed by in-situ reflection high energy electron diffraction, atomic force microscopy, X-ray reflectivity, and, X-ray diffraction. These films are found to be insulting and exhibit spin-glass behavior at low temperatures. The study offers an opportunity to tune the competition between charge/orbital ordering and ferromagnetism in half-doped manganites through heterostructure engineering.
