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…

Possible scenario of the spatially separated Fermi-Bose mixture in the superconductive bismuthates Ba_{1-x}K_xBiO_3
M. Yu. Kagan, A. P. Menushenkov, K. V. Klementev +1
A new scenario for superconductivity in the bismuthates based on the concept of a spatially separated Fermi-Bose mixture is proposed. In the framework of this scenario we qualitati…
