- 論文の詳細を見る
The magnetic relaxation of high T. superconducting thin films was studied. In the ntype NdCeCu0 film, the significantly large relaxation was observed even in a low fernperature region below 20 K, as compared with other p type oxide superconductingfilms. In order to analyze the data, a phenomenological model was presented. In thismodel, we used the time variable pinning potential barrier for the flux creep, combined with a classical relaxation equation. The activation energy defined as height ofpotential barrier at t= cX) can be calculated to be 0.01 eV, 0.12 eV and 0.19 eV forNdCeCu0, TlBaCaCu0 and ErBaCuO films, respectively.[magnetic relaxation, superconductor, thin films, activation energy, time depen- ll dent potentiall
