We report on the first finding that an insulator to metal transition (i.e. Verwey transition) of magnetite (Fe 3 O 4 ) takes place at absolute zero temperature as a function of pressure. In order to investigate the Verwey transition, we measured the

We have measured the valence-band photoelectron spectra of (La 1- x Sr x ) 2 CuO 4-δ single crystals. Spectra obtained at low temperatures (30–80 K) are similar to each other as well as the results reported so far: The intensity at the Fermi level

Ultraviolet photoemission spectra have been measured for Ce 2 Sb, CeBi 0.9 Te 0.1 and CeSe by use of synchrotron radiation to study their electronic structures especially to study the origin of the double peak structures. We have observed the same do

Photoelectron spectra have been measured on RbF in the photon energy region where 3 d electrons of the Rb + ion are excited. Two features appearing on the high-binding-energy side of the Rb + 4 s line and previously assigned to the configuration-inte

CeP 0.9 N 0.1 single crystal was grown. Unexpectedly, its lattice constant 5.953 A was slightly larger than 5.932 A of CeP. The electrical resistivities were measured under high pressures of up to 8.5 GPa in the temperature range from 300 down to 2 K

We have determined the Pauli susceptibility of the third stage of the “normal” and “residual” HNO 3 Graphite Intercalation Compounds (GICs). Using the π band structure of two-dimensional graphite, the charge transfer ratio was estimated. Thi

Mn 3 d states in Cd 1- x Mn x Y ( Y = S, Se and Te have been investigated by using synchrotron radiation photoemission. The Mn 3 d partial density-of-states spreads over the whole valence bands as a result of strong p-d hybridization with a prominent

The electronic structure of K0.9Mo6O17, which is a quasi-two-dimensional charge-density-wave (CDW) system, has been studied by ultraviolet photo-emission spectroscopy (UPS). Angle-integrated spectra were measured in the photon energy range from 32 to

The vacuum ultraviolet photoemission spectra of quasi-one-dimensional charge density wave ( CDW ) system, (TaSe4)2I, were measured for photon energies between 32 and 100 eV at room temperature ( in the normal phase ) and at about 100 K ( in the CDW p
