Magnetic relaxation was measured on a {kappa}-(ET){sub 2}Cu(N(CN){sub 2})Br(ET=BEDT-TTF) single crystal for H//b (perpendicular to the conducting layers) at 6K. The relaxation rate, dM/dlnt was found to have a maximum at 30 G. This maximum in the relaxation rate is thought to be the field of full penetration, H*, and agrees with the peak observed in the magnetization measurements for H//b at 6K. The field dependence of the relaxation rate can be described by a thermally activated flux creep model where U{sub 0}{approximately}8.3 meV. 7 refs., 3 figs.
