Investigation of Cu₂O-Based Diluted Magnetic Semiconductor by Mechanical Milling

抄録

  Diluted magnetic semiconductor of transition metal doped Cu₂O has been studied to realize the new room temperature ferromagnetic materials for the spintronics devises. Commercial TM oxides and Cu₂O. were used as the precursors which were mechanically milled by the planetary ball mill with WC vial and balls at 0～700 rpm for 15 minutes. Only vanadium was successfully doped into Cu₂O. These V-doped samples showed weakly ferromagnetic properties at room temperature.
