主 题:magnetization relaxation relation
摘 要:When the applied field Ba=μ0 H_(a)(H_(a)H_(p))is perpendicular to the surface of a disk-shaped superconducting thin film with the full penetrated field H_(p),the radius R,and the thickness d,a quantitative relation between the average fieldand the magnetization M is described by=μ_(0)[H_(a)+(0.81 d/R)M]for R»d,where the termμ0(0.81 d/R)M also is the average self-field of the *** this relation with the magnetic flux conservation equation and the Arrhenius relation,the effective activation energy is extracted from the experimental magnetization relaxation and the dynamic magnetization relaxation,respectively.
