Impedance of a type-II superconductor with a surface superconductivity
Govorkov S. A., Il'ichev E. V., Tulin V. A.
The surface impedance of a type-II superconductor with a surface superconductivity was studied experimentally. Small changes in the external magnetic field lead to a nonmonotonic behavior of the surface impedance. A qualitative model is proposed for the observed effect.
