Microwave Response of the Superconducting YBa2Cu3O9−x Ceramics
Abstract The interaction of the YBa2Cu3O9−x ceramics with the microwave field of frequency ω/2π=9,3 GHz has been studied experimentally in a wide range of temperatures. The superconducting transition was registered according to variation of the high-frequency conductivity of the sample. Radiation of the doubled 2ω and tripled 3ω frequencies was observed on increasing the amplitude of the alternating field. Temperature dependences of harmonics of the incident-wave intensities and of the external magnetic field have been investigated. Two mechanisms of nonlinearity, describing qualitatively the experimental results are proposed.
