- Using results of surface impedance measurements, the penetration of ac field into a melt-textured YBa$\text{}_{2}$Cu$\text{}_{3}$ O$\text{}_{7-δ}$ slab was investigated. We obtained a linear correlation between the surface impedance and ac frequency. The impedance curve shifts towards higher temperatures - 0.9 K per decade of the frequency increase, for dc magnetic fieldμ$\text{}_{0}$H$\text{}_{dc}$≤8×10$\text{}^{-3}$ T. This is an evidence of thermally activated flux creep. A plateau in the temperature dependence of the real impedance part was observed at approximately 88 K.
