AbstractThe temperature spectra of internal friction for Zn doped ceramic YBa 2 (Cu 1-x Zn x ) 3 O 6+δ are presented with zinc content x varying from 0 to 0.1. Two thermally activated peaks (P1, P2) near the superconducting transition temperature T c were found to show different behaviours upon zinc doping: the peak at 110 K (P1) decreases rapidly with increasing of x while another one at 120 K (P2) has no significant change. The relaxation mechanism of P1 is interpreted in terms of jumps of apical oxygen atoms between off-centred positions produced by the Jahn-Teller effect. The effect of zinc substitution on the depression of superconductivity is also discussed.
