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 (SrRuO₃)₁−(SrTiO₃)₅ superlattices and single-unit-cell-thick SrRuO₃ samples that are capped with SrTiO₃. We achieve samples of exceptional quality. In these samples, the electron systems comprise only a single RuO₂ 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.
