High quality PrO epitaxial thin films were synthesized for the first time using pulsed laser deposition, and their magnetic and electrical properties were evaluated. PrO exhibited ferromagnetic behavior in field cooling (FC) below 30 K, and the spontaneous magnetization at 2 K was estimated to be about 0.03 μB/f.u. On the other hand, electric conduction shows metallic behavior, and the anomalous Hall effect with hysteresis was observed below 20 K. PrO has a possibility to be an itinerant ferromagnet with near-zero spontaneous magnetization at the Curie temperature of about 30 K.
