| Outline of Final Research Achievements |
Interplay between 4f-localized spins on Lanthanide atoms and Charge-density-waves on conducting bands is investigated in the rare earth intermetallic compound, RNiC2 system. The conduction bands are constructed of d-orbital of Lanthanide atoms and Nickel atoms and p-orbital of Carbon atoms. For this purpose, we have developed a Guinier-type x-ray monochromatic Laue Camera down to 3 K of the lowest temperature and up to 10 T of the highest magnetic field. Employing this camera, we have clarified relationships between the magnetic order of 4f-localized spin and the CDWs on the conduction bands in the field-induced structural phase transition of (Nd, Dy)NiC2.
In addition to that, origin of the commensurate phase of YNiC2 has been revealed performing a single crystalline structure analysis method.
