Experimental study of thermomagnetomechanical instabilities in superconducting composites. II: Dynamics of normal zones

The dynamics of normal zones in superconducting Cu--Nb, Cu--NbTi, and bronze--Nb sub 3 Sn composites, arising from the development of various thermomagnetomechanical instabilities, have been investigated. It is shown that, even when there is no transport current, normal zones may be macroscopic in s...

Description
Summary:The dynamics of normal zones in superconducting Cu--Nb, Cu--NbTi, and bronze--Nb sub 3 Sn composites, arising from the development of various thermomagnetomechanical instabilities, have been investigated. It is shown that, even when there is no transport current, normal zones may be macroscopic in size (of the order of cm). 12 ref.--AA
