| Outline of Annual Research Achievements |
This year, the adsorption and absorption of magnetic atoms represented by Co on bilayer graphene nanosheets and the second is the interaction of gas molecules on the surface of metal electrodes. It is found that the crystal fields with C3v symmetry split the Co’s 3d orbitals into two doubly degenerate irreducible representations E1 (dxz,dyz) and E2 (dx2-y2,dxy) and a one-dimensional representation A1(d3z2-r2). Further, the estimated magnetic exchange interactions exhibit ferromagnetic exchange coupling between the localized spins of Co.
To model the simplest molecule-surface interactions, H2 adsorption on Pd(210) has been investigated. It is found that H2 is in the molecularly chemisorbed state and the adsorption is characterized by a highly anisotropic potential energy surface. Rotational-vibrational calculations show that two lowest bound state levels belong to J=0 and 1 species, respectively. It is further known that H2 adsorbates drastically affect the electronic properties of the metal surface. Since H2 can practically be separated into two nuclear spin isomers, nuclear spin states interconversion is found to proceed at a very fast rate on Pd(210).This results to a molecule in a different nuclear spin state and a magnetic metal surface.
The accounts of this research have been published to international scientific journals and presented in numerous domestic and international conferences.
