First order valence transition: Neutron diffraction, inelastic neutron scattering and x-ray absorption investigations on the double perovskite Ba2PrRu0.9Ir0.1O6
J. Sannigrahi, D. T. Adroja, C. Ritter +8
Bulk studies have revealed a first-order valence phase transition in BaPrRuIrO (), which is absent in the parent compounds with (Pr…
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…
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…
Crystal structure and superconducting properties of hexagonal lithium-niobium oxynitride
Teruki Motohashi, Masahiko Ito, Yuji Masubuchi +2
A hexagonal oxynitride (Li0.88_0.12)Nb3.0(O0.13N0.87)4 was synthesized through ammonia nitridation of LiNb3O8. The structural analysis revealed that this oxynitride consists of alt…
Emergence of magnetic long-range order in frustrated pyrochlore NdIrO with metal-insulator transition
K. Tomiyasu, K. Matsuhira, K. Iwasa +7
In this study, we performed powder neutron diffraction and inelastic scattering measurements of frustrated pyrochlore NdIrO, which exhibits a metal-insulator transition…
