摘要：

The surface resistance of HTSC ceramic YBa2Cu3O6+x for a HF field with wavelength 70 cm is studied by registration of the intrinsic Q-factor of a coaxial short-circuited resonator made of the investigated material. It is established that, at T = 4.2 K, rs changes slowly with H, apart from the range below Hc1, where the dependence is quadratic. The value of rs is 0.02 ohm at T = 4.2 K and 0.7 ohm at T = 300 K, which supports the presence of gigantic ferroelectric absorption of the power of the HF field.
