Enhanced ferromagnetic transition temperature induced by a microscopic structural rearrangement in the diluted magnetic semiconductor GeMnTe
M. Kriener, T. Nakajima, Y. Kaneko +7
The correlation between magnetic properties and microscopic structural aspects in the diluted magnetic semiconductor GeMnTe is investigated by x-ray diffraction and m…
Heat-Treatment-Induced Switching of Magnetic States in the Doped Polar Semiconductor GeMnTe
M. Kriener, T. Nakajima, Y. Kaneko +8
Cross-control of a material property - manipulation of a physical quantity (e.g., magnetisation) by a nonconjugate field (e.g., electrical field) - is a challenge in fundamental sc…
Magnetic Frustration in a Mn Honeycomb Lattice Induced by Mn-O-O-Mn Pathways
H. Wadati, K. Kato, Y. Wakisaka +9
We investigated the electronic structure of layered Mn oxide Bi3Mn4O12(NO3) with a Mn honeycomb lattice by x-ray absorption spectroscopy. The valence of Mn was determined to be 4+…
Roles of two successive phase transitions in new spin-Peierls system TiOBr
T. Sasaki, M. Mizumaki, T. Nagai +5
In this sturdy, we determine the roles of two successive phase transitions in the new spin-Peierls system TiOBr by electron and synchrotron X-ray diffraction analyses. Results show…
Pressure/temperature/substitution-induced melting of A-site charge disproportionation in Bi_(1-x)La_(x)NiO_3 (0 =< x =< 0.5)
S. Ishiwata, M. Azuma, M. Hanawa +8
Metal-insulator transitions strongly coupled with lattice were found in Bi1-xLaxNiO3. Synchrotron X-ray powder diffraction revealed that pressure (P ~ 3 GPa, T = 300 K), temperatur…
The Metal-Insulator Transition in Y1-xCaxTiO3 Caused by Phase Separation
K. Kato, E. Nishibori, M. Takata +6
In order to explore the origin of the Metal-Insulator (M-I) transition, the precise crystal structures of the hole-doped Mott insulator system, Y1-XCaXTiO3 (x=0.37, 0.39 and 0.41),…
