Electronic structure of the novel high- ferromagnetic semiconductor (Ga,Fe)Sb: x-ray magnetic circular dichroism and resonance photoemission spectroscopy studies
Shoya Sakamoto, Nguyen Thanh Tu, Yukiharu Takeda +11
The electronic structure and the magnetism of the novel ferromagnetic semiconductor (Ga,Fe)Sb, whose Curie temperature can exceed room temperature, were investigated by…
Nematicity in the pseudogap state of cuprate superconductors revealed by angle-resolved photoemission spectroscopy
S. Nakata, M. Horio, K. Koshiishi +9
The nature of the pseudogap and its relationship with superconductivity are one of the central issues of cuprate superconductors. Recently, a possible scenario has been proposed th…
Local Magnetic States of the Weakly Ferromagnetic Iron-Based Superconductor SrVFeAsO Studied by X-ray Magnetic Circular Dichroism
Masafumi Horio, Yukiharu Takeda, Hiromasa Namiki +10
We have performed x-ray magnetic circular dichroism (XMCD) measurements on the iron-based superconductor SrVFeAsO to study the origin of weak ferromagnetism (WFM) repor…
Strain-Engineering Mott-Insulating LaCuO
O. Ivashko, M. Horio, W. Wan +15
The transition temperature of unconventional superconductivity is often tunable. For a monolayer of FeSe, for example, the sweet spot is uniquely bound to titanium-o…
Three-Dimensional Fermi Surface of Overdoped La-Based Cuprates
M. Horio, K. Hauser, Y. Sassa +24
We present a soft x-ray angle-resolved photoemission spectroscopy study of the overdoped high-temperature superconductors LaSrCuO and LaEuSrCu…
Spin-Orbital Excitations in CaRuO Revealed by Resonant Inelastic X-ray Scattering
L. Das, F. Forte, R. Fittipaldi +19
The strongly correlated insulator CaRuO is considered as a paradigmatic realization of both spin-orbital physics and a band-Mott insulating phase, characterized by orbita…
Two-dimensional type-II Dirac fermions in layered oxides
M. Horio, C. E. Matt, K. Kramer +11
Relativistic massless Dirac fermions can be probed with high-energy physics experiments, but appear also as low-energy quasi-particle excitations in electronic band structures. In…
Angle-resolved photoemission spectroscopy of the low-energy electronic structure of superconducting PrCuO driven by oxygen non-stoichiometry
M. Horio, Y. Krockenberger, K. Koshiishi +8
Bulk crystals of electron-doped cuprates with the T'-type structure require both Ce substitutions and reduction annealing for the emergence of superconductivity while the reduction…
