Abstract
The second harmonic in the dependence of a superconducting current on the p hase difference of superconducting wave functions of the electrodes was obs erved experimentally in Nb/Au/(001)YBa2Cu3Ox heterojunctions. Possible reas ons for its appearance were discussed within the framework of a mixed (d +/ - s) symmetry order parameter of YBa2Cu3Ox. (C) 2001 MAIK "Nauka/ Interperi odica".
