  • Abstract
    An investigation was conducted of the RF properties of high-Tc superconductors over a wide range of temperatures, frequencies and RF field amplitudes. Both bulk polycrystalline samples and thick films on silver substrates were tested. At 150 MHz and 4.2 K, surface resistances of 18 μΩ at low RF field and 3.6 mΩ at an RF field of 270 G were measured. All samples showed a strong dependence of the surface resistance on RF field. However, no breakdown of the superconducting state was observed up to the highest field achieved (320 G)
