| Outline of Final Research Achievements |
We studied the derivation of Dzyaloshinsky-Moriya interaction on 5d electron systems and the phenomena related with Dzyaloshinsky-Moriya interaction.(1) We derived the Dzyaloshinsky-Moriya interaction between multipoles of 5d electronic systems.(2)We solved the magnetic phase diagram of CsCuCl3 under the high pressure and the magnetic field parallel to c axis.(3) We clarified the renormalization effect of antisymmetric spin-orbit interaction near the magnetic quantum critical point.(4) We derived the Dzyaloshinsky-Moriya interaction based on RKKY interaction at the interface of ferromagnet and heavy metal heterostructure.
