The structural and perpendicular magnetism of molecular beam epitaxy grown (FePt)1-xMnx films with doping concentration of x = 0, 1%, 2%, 3%, 4%, 5% were discussed. It was found that the perpendicular magnetic anisotropy effect of the (FePt)1-xMnx film tends to decrease with the increase of Mn doping for x >1%. The analysis showed that the perpendicular magnetic anisotropy constant were of about 1.3×107 and 1.6×107 erg/cm2 for x=0% and x=1%, respectively.
