Abstract

Rocksalt NdO (001) epitaxial thin films were synthesized. Contrary to paramagnetic NdO bulk polycrystal in previous studies, NdO epitaxial thin films showed ferromagnetism with a Curie temperature of 19.1 ± 1.8 K, originating from dominant direct Nd-Nd exchange interaction owing to the small intercationic distance. In addition, negative magnetoresistance and an anomalous Hall effect were observed.
