Observation of the effect of superconducting state on the mobility of dislocations in Nb
Karpov I.V. , Leiko E.B., Nadgornyi E.M.
The mobility of dislocations in a thermally activated region of motion of dislocations in niobium single crystals at 4.2 К was measured and a noticeable difference between the mobilities of dislocations in the normal state and the superconducting state was observed.
