New Hydrocarbon Superconductor on the Verge of Metal-Insulator Transition: Electronic Structures and Magnetic Properties of K3picene
New Hydrocarbon Superconductor Verge of Metal-Insulator Transition: Electronic Structures Magnetic Properties of K3picene
2010/11/22
We have investigated the electronic structures and magnetic properties of of K3picene, which
is a first hydrocarbon superconductor with high transition temperature Tc=18K. We have shown
that the met...
Electronic structure of an antiferromagnetic metal: CaCrO3
Electronic structure antiferromagnetic metal: CaCrO3
2010/11/19
We report on the electronic structure of the perovskite oxide CaCrO3 using valence-band, corelevel,and Cr 2p − 3d resonant photoemission spectroscopy (PES). Despite its antiferromagnetic order, ...
Orbital Order, Metal Insulator Transition, and Magnetoresistance-Effect in the two-orbital Hubbard model
Orbital Order Metal Insulator Transition Magnetoresistance-Effect
2010/11/19
We study the effects of temperature and magnetic field on a two-orbital Hubbard model within
dynamical mean field theory. We focus on the quarter filled system, which is a special point in the phase ...

Temporal behavior inverse spin Hall voltage magnetic insulator-nonmagnetic metal structure
2010/11/18
The time dependence of an inverse spin Hall (iSHE) voltage in a magnetic insulator (yttrium
iron garnet, YIG)-nonmagnetic metal (platinum, Pt) structure is studied. A flow of spin-polarized electrons...
Field-induced water electrolysis switches an oxide semiconductor from an insulator to a metal
Field-induced water electrolysis switches oxide semiconductor
2010/11/23
Water is composed of two strong electro-chemically active agents, H+ and OH– ions,for oxide semiconductors though water has never been utilized as an active electronic material. Here we demonstrate th...

2010/11/17
We report results of NMR experiments on the ruthenium oxide Hg2Ru2O7 with the py-rochlore structure, which exhibits a metal-insulator transition at TMI = 107 K. In the metallic
phase above TMI, the n...
