| Research Abstract |
Ordered alloys show various excellent magnetic properties, and they are promising as materials for next-generation electronics. From a viewpoint of application to magnetic storage technology, it is expected to develop new ordered alloys with multi-functionalities. In this study, we have attempted to fabricate novel ordered alloys with a high magnetic anisotropy, a high spin-polarization, and a low magnetic damping constant by employing a monoatomic layer deposition method. A stacked structure with L1_0-type FePt, CoPt and Co_2MnSi and an L1_0-type FeNi thin films were successfully fabricated, and various properties of the materials were investigated.
