This paper reviews the crystal structure and magnetic and magneto-optical properties of CoPt, MnPt3, CrPt3, MnAl and MnGa films with an ordered phase as well as dot patterns fabricated on these films. CoPt film grown on a MgO (111) substrate at 300˚C had an L11 phase and exhibited a large perpendicular anisotropy. CrPt3 films, which had a (111) orientation and L12 phase, showed a large perpendicular anisotropy due to the magneto-elastic effect. By utilizing the change from L12 to a disordered phase caused by low-dose Kr + ion irradiation, dot patterns were prepared on CrPt3 film with a flat surface. It was found that a CoGa buffer layer was effective at growing thinner L10 MnAl and MnGa films on a MgO (001) substrate while keeping a (001) orientation. In the case of fabricating MnGa on SiO2/Si substrates, a buffer layer of CoGa/Cr/MgO/Cr/NiTa was necessary to grow L10 MnGa with a (001) orientation.

The magnetic and magneto-optical properties have been investigated for ordered (Mn1−xFex)Pt3 alloy (0<x<0.6) films, prepared by annealing (Mn-Fe)/Pt multilayer films at 800 °C. The Kerr spectrum of the MnPt3 film had a large negative peak value of −1.18° at 1.24 eV, and showed a small positive peak around 3.2 eV. With increasing Fe content x, the peak value at 1.24 eV decreased in magnitude and the position of the peak shifted towards lower energy side. Furthermore, another peak appeared in the Kerr spectra around 2.3 eV for x>0.24. The spectral analysis of the diagonal component of dielectric tensor and the off-diagonal component of conductivity tensor showed that all the peaks mentioned above were attributed to interband transitions.
