On the Problem of the Staggered Field in CuGeO3 Doped with Magnetic Impurities
S. V. Demishev
The magnitude of the staggered field is calculated from the EPR data for CuGeO3 doped with Co and Fe magnetic impurities. It is found that this parameter demonstrate an anomalous t…

Quantum critical point in CuGeO3 doped with magnetic impurities
S. V. Demishev, Y. Inagaki, M. M. Markina +7
Using high frequency (up to 450 GHz) ESR and low temperature specific heat measurements we find that insertion of 1% Fe and 2% Co damps spin-Peierls and Neel transitions and for T<…

Critical behavior in NaV2O5: the case of dielectric function and the aspect of universality
S. V. Demishev, A. A. Pronin, N. E. Sluchanko +3
Temperature dependence in the interval 4.2-300 K and the critical behavior of the dielectric function along c-axis in NaV2O5 have been studied in the frequency range 1 MHz-1 GHz. T…
