The growth of the magnetic MnGeAsP films with the nominal composition MnGe(As 1-xP x) 2 on GaAs was discussed.It was found that the films were grown keeping the Mn, Ge and As fluxes constant while varying the P flux. It was observed that the superconducting quantum interference device magnetic measurements showed clear change in the magnetic properties as phosphorus was introduced into the films. Analysis shows that the measured Curie temperatures were over 380 K for P/As ratios larger than 2 which was higher than that of a nominal MnGeAs 2 and MnGeP 2 film.
