Magnetic order in pyrochlore iridate NdIrO probed by muon spin relaxation
Hanjie Guo, Kazuyuki Matsuhira, Ikuto Kawasaki +4
Muon-spin relaxation results on the pyrochlore iridate NdIrO are reported. Spontaneous coherent muon-spin precession below the metal-insulator transition (MIT) temperat…
Robustness of Quantum Criticality of Valence Fluctuations
Shinji Watanabe, Kazumasa Miyake
The mechanism of emergence of robust quantum criticality in Yb- and Ce-based heavy electron systems under pressure is analyzed theoretically. By constructing a minimal model for qu…
Ab initio GW calculation for organic compounds (TMTSF)2PF6
Kazuma Nakamura, Shiro Sakai, Ryotaro Arita +1
We present an ab initio GW calculation to study dynamical effects on an organic compound (TMTSF)2PF6. Calculated polarized reflectivities reproduce experimental plasma edges at aro…
Giant Magnetoresistance Effect in the Metal-Insulator Transition of Pyrochlore Oxide Nd2Ir2O7
Kazuyuki Matsuhira, Masashi Tokunaga, Makoto Wakeshima +2
We investigated the magnetoresistance (MR) effect of the pyrochlore oxide Nd2Ir2O7, which shows a metal-insulator transition at T_MI =33 K. A small positive MR effect was observed…
