| Research Abstract |
The recording density of magnetic storages such as a hard disc equipped in a personal computer is now rapidly increasing, and a volume of one bit is getting smaller and smaller. Inexpensive magnetic materials with high uniaxial magnetic anisotropy are strongly needed. In this study, we have attempted to fabricate novel, highly anisotropic magnetic materials by employing conventional elements of iron and nickel. An L1_0 type FeNi alloy was successfully fabricated, and various properties of the material were investigated.
