Title: Ferromagnetism and Conductivity in Atomically Thin SrRuO 3

Abstract

Atomically thin ferromagnetic and conducting electron systems are highly desired for spintronics, because they can be controlled with both magnetic and electric fields. We present ( SrRuO 3 ) 1 - ( SrTiO 3 ) 5 superlattices and single-unit-cell-thick SrRuO 3 samples that are capped with SrTiO 3 . We achieve samples of exceptional quality. In these samples, the electron systems comprise only a single RuO 2 plane. We observe conductivity down to 50 mK, a ferromagnetic state with a Curie temperature of 25 K, and signals of magnetism persisting up to approximately 100 K.
