Pt50Co50 alloy films have been grown by MBE method onto heated MgO(100) and (111) substrates. It is found that films grown on a (111) substrate at 300°C have the CuPt type structure, whereas films grown onto (111) substrate at 500°C and onto (100) substrate at 300°C and 400°C form in the PtCo ordered phase with AuCu structure. The film of the CuPt type exhibits a very large perpendicular magnetic anisotropy of 1.0×106 J/m3 , due to the layered structure along the film normal direction. The spectrum of Kerr rotation θk of the film with CuPt structure is considerably different from that of AuCu structure, not exhibiting a maximum around 4.0 eV but showing a peak at 1.4 eV
