Abstract
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.
