NEW EXPERIMENTAL CRITERION OF THE BEREZINSKII−KOSTERLITZ−THOULESS TRANSITION
Authors:
M.A. Vasyutin, A.I. Golovashkin, N.D. Kuzmichev.



Abstract:
Based on the experimental study of YBa2Cu3O7−x single crystal nonlinearity near Tc, a new criterion for observing the Berezinskii−Kosterlitz−Thouless (BKT) transition in cuprate HTSC compounds was proposed. The criterion consists in the existence of the maximum in the dependence of the voltage of the second harmonic of the sample response signal excited by alternating current on the direct bias current. It was shown that the position of the second harmonic maximum is independent of temperatures near Tc, which is consistent with the BKT transition independence of the measuring current.
