Abstract

Measurements of magnetic-field-dependent microwave absorption as a function of both the temperature (4 K to T_c) and cooling field (0–10 kG) are reported. Below a certain characteristic temperature, T* < T_c, the absorption strongly depends on the magnetic field in which the samples are cooled. The characteristic temperature T* scales with T_c.
