Abstract

Transition metal doped CuO has been studied to realize the new room temperature ferromagnetic materials for the spintronics devises. Commercial transition metal oxides and CuO were used as the precursors, and they were mechanically milled by the planetary ball mill with WC vial and balls at 500 rpm for 15 minutes. V, Mn and Fe were successfully doped into CuO. These samples showed various magnetic properties at room temperature.
