Outline of Final Research Achievements |
Photoemission study has been applied to the following multi-orbital materials in order to discuss the mechanism for their novel properties from the viewpoint of the electronic structures. (i) Magnetic shape memory material Ni2MnGa, (ii) MnRh, an antiferromagnet with possible high Neel temperature, (iii) Possible half-metallic material CrO2, (iv) KxFe2-ySe2, a superconductor showing spatial phase separation with antiferromagnetism, (v) a novel superconductor La(O,F)BiS2 which exhibits marked spin-orbit interactions.
