Description
Investigation into electrodynamic properties lower than the superconducting transition temperature is conducted in the presence of magnetic field of up to 716 kA/m using polycrystalline samples of La1.8Sr0.2CuO4 with Tc=30 K and YBa2Cu3O7 with Tc=87 K. The field and temperature dependences of the surface impedance obtained allowed one to evaluate the first critical field magnitude which made up Hc=9.6 kA/m for YBa2Cu3O7. The presence of bends in the dependences investigated is supposedly explained by the existence of several energy gaps
