| Abstract: | A one to one map is established between the magnetic-hysteresis-loop (MHL) measurements and the magnetization relaxation measurements performed at the same external field, noticeably keeping no uncertainties of such factors as the microscopic attempt frequency v 0 and the hopping distance l hop for pinned flux motion. By utilizing this map, we are able to construct and extend the magnetization relaxation data from the corresponding reported MHL measurements. The present algorithm proves to be reliable and simple for investigations of the U(J) behavior and relaxation effects. |
