Inversion-induced orbital and exchange disorders in antiferromagnetic A-site spinel CoAl2O4
Takashi Naka, Hiroaki Mamiya, Kanji Takehana +6
The inversion and volume effects on magnetism in a spinel-type magnetically frustrated compound, CoAl2O4, and its gallium-substituted system, CoAl2-xGaxO4, were investigated. Magne…
Composition induced metal-insulator quantum phase transition in the Heusler type Fe2VAl
Takashi Naka, Artem M. Nikitin, Yu Pan +6
We report the magnetism and transport properties of the Heusler compound Fe2+xV1-xAl at -0.10 < x < 0.10 under pressure and a magnetic field. A metal-insulator quantum phase transi…
Quasi-particles ultrafastly releasing kink bosons to form Fermi arcs in a cuprate superconductor
Y. Ishida, T. Saitoh, T. Mochiku +3
In a conventional framework, superconductivity is lost at a critical temperature (T_c) because, at higher temperatures, gluing bosons can no longer bind two electrons into a Cooper…
Multistage ordering and critical singularities in Co1-xZnxAl2O4 (0 < x < 1):Dilution and pressure effects in a magnetically frustrated system
Takashi Naka, Koichi Sato, Yoshitaka Matsushita +9
We report comprehensive studies of the crystallographic,magnetic, and thermal properties of a spinel-type magnetically frustrated compound, CoAl2O4, and a magnetically diluted syst…
Correlation between doping induced disorder and superconducting properties in carbohydrate doped MgB2
J. H. Kim, S. X. Dou, Sangjun Oh +4
A comprehensive study of the effects of carbohydrate doping on the superconductivity of MgB2 has been conducted. In accordance with the dual reaction model, more carbon substitutio…
Doping-dependence of nodal quasiparticle properties in high- cuprates studied by laser-excited angle-resolved photoemission spectroscopy
K. Ishizaka, T. Kiss, S. Izumi +11
We investigate the doping dependent low energy, low temperature ( = 5 K) properties of nodal quasiparticles in the d-wave superconductor BiSrCaCuO (B…
