Surface Impedance of Bismuth at Large Electromagnetic-wave Amplitudes
Dolgopolov V.T., Margolin L.Ya.
It has been observed that at helium temperatures and alternating electromagnetic-fieId amplitudes above a certain critical value there exists a magnetic-field region in which bismuth samples can have several stable states characterized by different dependences of the derivatives of the real and imaginary parts of the surface impedance on the magnetic field.
