Third-harmonic microwave radiation of the BiSrCaCuO superconducting single crystal was studied. Two modes of microwave field-sample interactions were observed. In a weak field, a strong increase in the intensity of radiation after switching on a cons

The third harmonic generation by monocrystalline Bi-Sr-Ca-Cu-O under the influence of high microwave power at frequency 9 GHz has been investigated. Two modes of operation have been found. For comparatively weak driving forces we observed that dc mag

The generation of a microwave second harmonic by a YBCO single crystal in a dc magnetic field was studied. We found that the signal existed only when there was a direct screening current. As a result, the pinning current as a function of magnetic fie

We present the results of experimental measurements of nonlinear microwave absorption in thin circular high-temperature superconducting YBCO films. The sample was located in a field of two waves - weak nonmodulated and strong modulated with rectangul

Nonlinear microwave absorption of the thin superconducting film is studied. It is shown that nonlinearity could not be explaned by heating of the sample. The conception of the vorteces generated by the microwave field gives results in agreement with

The electromagnetic excitation of standing sound waves in the plates of a high- T c ceramic (YBa 2 Cu 3 O 7−x , EuBa 2 Cu 3 O 7− x ) was used to study the dependence of the frequency of acoustic resonances on the magnetic field aligned parallel t

The electromagnetic excitation of standing sound waves in the plates of a high-Tc ceramics (YBa2Cu3O7−x, EuBa2Cu3O7−x) was used to study the dependence of the frequency of acoustic resonances on the magnetic field aligned parallel to the plate pl
