| Outline of Final Research Achievements |
Toward generation and remote control of the motion "molecular oscillation and rotation" in a magnetic molecular machine, we performed a theoretical study on a relaxation of an excited spin. Here, the relaxation is considered to originate from a spin-molecular motion (oscillation and rotation) interaction V. For this V, spin direction dependence of 3d orbitals with spin-orbit interaction and crystal field plays an important role. In addition, a phenomenon to observe such dependence is the anisotropic magnetoresistance (AMR) effect. In this study, we theoretically investigated the spin-direction dependence of the 3d orbitals and the AMR effect. As a result, we obtained new insights about the spin-direction dependence of shape of the 3d orbitals and the crystal field effect on the AMR ratio.
