Depinning Line of High-Tc Superconductor HgBa2CuO4+x
-
Abstract
Mechanical dissipation of high-Tc superconductor compound HgBa2CuO4+x as a function of temperature was measured with the vibrating reed technique. The depinning line determined from the peak temperature of internal friction was found to be higher than that of Bi-based sample but lower than that of Y-based one.
