FIG. 1.

Magnetic-field dependence of the critical current density measured at frequencies of (▵) and (◻) and the dynamic relaxation rate determined from them (●) for samples AC86 (a) and PP8 (b). The solid lines are linear approximations of the experimental data on the part with constant and on the part with a logarithmic fall. The arrows indicate the points of intersection of the approximating lines. At the points of intersection the field had the values , 2,3 and , respectively, for the curves at frequencies of 3033 and and for the curve in the case of sample AC86, and 13.3, 11.8, and for sample PP8. .

FIG. 2.

Temperature dependence (in terms of the reduced temperature ) of the dynamic relaxation rate for sample PP8 without a dc field (◻) and in a dc magnetic field of (▴) and (엯). The solid lines connect the points. The dashed line show an approximation of the dependence in the form . The values of equal , , and in fields of 0, 10, and , respectively.
