| Outline of Final Research Achievements |
Magnetic anisotropy and coercivity are important physical properties for magnetic materials. We have investigated Co and Fe single layer nano structure on a heavy metal W surfaces in order to enhance magnetic anisotropy and coercivity. We have successfully prepared single atomic wires of Co and Fe on W(112) surface, which show 10~100 times larger magnetic anisotropy energies compared to those for bulk materials and have giant coercivity of ~3 T. We have revealed that even for common 3d transition metals, Co and Fe, precise control of their nano structures give rise to large magnetic anisotropy and coercivity.
