説明
<p> 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.</p>
