Quantum Critiality and Collective Effects in Low Dimensional Magnet CuGeO3 Probed by High Frequency EPR
S. V Demishev, A. V. Semeno, A. A. Pronin +8
For the CuGeO3 single crystals doped with 1% of Fe the quantum critical behavior in a wide temperature range 1-40 K is reported. The critical exponents for susceptibility along dif…
Disorder driven quantum critical behavior in CuGeO3 doped with magnetic impurity
S. V. Demishev, A. V. Semeno, N. E. Sluchanko +9
For the CuGeO3 doped with 1% of Fe the quantum critical behavior in a wide temperature range 1-40 K is reported. The critical exponents for susceptibility along different crystallo…
Magnetic Phase Diagrams with Possible Field-induced Antiferroquadrupolar Order in TbBC
Koji Kaneko, Hideya Onodera, Hiroki Yamauchi +3
Magnetic phase diagrams of a tetragonal antiferromagnet TbBC were clarified by temperature and field dependence of magnetization. It is noticeable that the N{é}el temperatu…
ESR study on the excited state energy spectrum of SrCu(BO) -a central role of multiple-triplet bound states
H. Nojiri, H. Kageyama, Y. Ueda +1
The excited state energy spectrum of a two-dimensional dimer system SrCu(BO) has been investigated by high field ESR. Various types of multiple-triplet bound states-exc…
Fermi Surface Study of Quasi-Two-Dimensional Organic Conductors by Magnetooptical Measurements
Y. Oshima, H. Ohta, K. Koyama +6
Magnetooptical measurements of several quasi-two-dimensional (q2D) organic conductors, which have simple Fermi surface structure, have been performed by using a cavity perturbation…
