Temperature Dependence of the Change of Rate of Plastic Deformation of Lead in Superconducting Transitions
Bobrov V.S., Gutmanas E .Yu.
It follows from the agreement between the temperature dependences of the experimentally determined ratio of the rates of plastic deformation of lead in the normal (N) and superconducting (S) states in SN transitions, on the one hand, and the function describing the ratio of the electronic viscosities in the S and N states, on the other, that the plastic deformation of Pb at helium temperatures is determined by electronic drag of the dislocations .
