Influence of the frequency on the electrical and magnetic properties of rod-shaped Y-Ba-Cu-O superconductor measured by the SRPM method

摘要

The temperatue dependence of resistivity rho and magnetic penetration depth lambda of a 10wt. percent Ag doped YBaCuO sample was measured by SRPM method on various frequencies under 1 MHz. rho and lambda are proportional to the power of 0.8 and 0.125 of frequency respectively. The frequency dependence of rho / lambda is proportional to the power of 2/3 of frequency. Therfore, it is confirmed that the sample reached the state of anomalous skin effect.
