Preparation of Ferromagnetic Cobalt Substituted TiO_2 (Anatase) Thin Films by Electrochemical Deposition

摘要

Dilute magnetic semiconductors (DMS), also known as semi-magnetic semiconductors, have stimulated considerable interest in recent years. Their combined ferromagnetic and semiconducting character is of particular interest for spin-tronics.2 However, most DMS cannot be used as room-temperature ferromagnets in practical spintronics applications because they possess low Curie temperatures.
