Query: Critical behavior in NaV2O5: the case of dielectric function and the
  aspect of universality   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. These data were analyzed together with literature
data concerning specific heat, magnetic losses and ultrasonic velocity. We
found that all results support the idea about universality of the critical laws
at the transition in NaV2O5 where different physical quantities demonstrate
identical shape of the anomaly. Considerable deviations from the standard
theory of the second order transition including asymmetry of the critical
behavior above and below transition and appearance of the anomalous background
are detected.
