New structural and magnetic aspects of the nanotube system Na2V3O7
O. Zaharko, J. L. Gavilano, Th. Straessle +11
We present new experimental results of low temperature x-ray synchrotron diffraction, neutron scattering and very low temperature (mK-range) bulk measurements on the nanotube syste…
Valence and Na content dependences of superconductivity in NaxCoO2.yH2O
H. Sakurai, N. Tsujii, O. Suzuki +5
Various samples of sodium cobalt oxyhydrate with relatively large amounts of Na ions were synthesized by a modified soft-chemical process in which a NaOH aqueous solution was…
Coexistence of a nearly spin-singlet state and antiferromagnetic long-range order in quantum spin system CuCdBO
Masashi Hase, Masanori Kohno, Hideaki Kitazawa +5
A 1/2 magnetization plateau in magnetic fields above 23 T and antiferromagnetic (AF) long-range order (AFLRO) in low fields were found in CuCdBO. Experimental results a…
Field-induced magnetic ordering in the Haldane system PbNi2V2O8
N. Tsujii, O. Suzuki, H. Suzuki +2
The Haldane system PbNi2V2O8 was investigated by the temperature dependent magnetization M(T) measurements at fields higher than H_c, with H_c the critical fields necessary to clos…
Infrared spectroscopy under multi-extreme conditions: Direct observation of pseudo gap formation and collapse in CeSb
T. Nishi, S. Kimura, T. Takahashi +4
Infrared reflectivity measurements of CeSb under multi-extreme conditions (low temperatures, high pressures and high magnetic fields) were performed. A pseudo gap structure, which…
Magnetic properties and thermal expansion of YbGaGe (0.9 <= x <= 1.5)
N. Tsujii, T. Furubayashi, H. Kitazawa +1
The composition dependence of the Yb valence and of the thermal expansion have been studied in the YbGaGe system. X-ray diffraction reveals that single-phased samples i…
