Abstract
It is found that HTSC single crystals share a common feature with cera mics - a change of the sign of the slope in the temperature dependence of the Ohmic resistance at certain frequencies, when the sign at dire ct current is positive. This feature was investigated on Y-, Er- and D y-based single crystals. The frequency, at which Ohmic resistance beco mes temperature-independent, is found to correlate with the dc transpo rt properties.
