Abstract
A normal-core model of type-II superconductors is used to calculate a contribution to the flux-flow viscosity arising from local temperature gradients in the core vicinity. The flux-flow resistivity versus temperature, according to this model, exhibits a minimum for impure, but not for pure, superconductors.Keywords
