Thin films of 5 % Co doped Cu2O were grown on single crystal (001) MgO substrates by pulsed laser deposition, without and with 0.5 % codoping with Al, V or Zn. Structural, electrical, and magnetic properties were studied. The films showed phase pure character under the chosen optimum growth conditions. Spin glass like behavior was observed in Co doped films without codoping. A clear ferromagnetic signal at room temperature was found only in the case of Co:Cu2O films codoped with Al.
