Flux Flow in a Current-Carrying Cylinder of Type 2 Superconductor in a Longitudinal Magnetic Field

抄録

In the resistive state of current-carrying type-2 superconducting cylinders with longitudinal magnetic fields, the existence of a helical structure composed of the flux-flow domain and the normal-like domain has been suggested experimentally.
Based on this helical structure, the expressions of the induced electric field and the induced paramagnetic magnetization are derived with the aid of the critical-state model. The present derivations are applicable only when the magnetic field generated by a transport current is smaller than the longitudinal magnetic field, and the results show fairly good agreements with the observed data of this range.
