Phase-pure, stoichiometric, unstrained, epitaxial (001)-oriented thin films have been grown on (001) substrates by reactive molecular-beam epitaxy. Magnetization measurements show antiferromagnetic behavior with , similar to bulk . Spectroscopic ellipsometry measurements reveal that films have a direct optical band gap of .
