Observation of lattice distortion in the low-dimensional quantum spin system TiOBr by synchrotron x-ray diffraction
Tomoyuki Sasaki, Masaichiro Mizumaki, Kenichi Kato +4
We report here on physical properties and lattice distortion in the new quasi-one-dimensional spin system TiOBr by x-ray diffraction experiment using synchrotoron radiation. Compar…
The enhancement of superconducting transition temperature in yttrium sesquicarbide system, Y2C3, with the maximum Tc of Tc=18K
G. Amano, S. Akutagawa, T. Muranaka +2
We discovered the enhancement of superconducting transition temperature, Tc, in yttrium sesquicarbide system with the maximum Tc of Tc=18K and their superconducting properties were…
Micro-Raman scattering investigation of MgB2 and RB2 (R=Al, Mn, Nb and Ti)
N. Ogita, T. Kariya, K. Hiraoka +5
Phonon spectra have been investigated by micro-Raman scattering from 290 to 20K. New peaks at 500 and 674 cm-1 appear below 250K in MgB2. These peaks are explained by the Fermi res…
Quantum and classical dynamics in complex one-dimensional antiferromagnets
A. Zheludev, S. Maslov, T. Yokoo +3
Of great recent interest in condensed matter physics are phenomena of coexistence of quantum and classical properties in the same material. Such duality occurs in certain mixed-spi…
