✦ Synopsis

The magnetic relaxation arising from thermally activated flux motion has been measured for the high-Jc YBa2Cu307 films prepared by chemical vapor deposition. The distribution of activation energies is discussed on the basis of a flux creep model proposed by Hagen and Griessen. The distrubution is related to the high-J c property of the YBa2Cu307 films.
