Abstract

Magnetization measurements were made on a polycrystalline sample of GdBa2Cu3O7 at different temperatures from 4.2 K up to TC=91 K. The saturated remanent magnetization (MRS) as a detailed function of temperature (T) was used to study the variation of the vortex flux pinning forces with (T). The sample has been fully saturated by applying a high magnetic field to establish the critical state. Our data reveals that the average vortex flux pinning forces scale according to the following empirical relation of MRS=at7+bt1/2, where t=1-T/TC, a, and b are constants.
