The Effect of an Applied Transverse Magnetic Field on the Flow Stress of Superconducting Lead

The intermediate state in type I superconductors of rod form subject to a transverse magnetic field is characterized by a laminar normal superconducting structure. This gives rise to temperature and field dependent minima in the thermal conductivity. The measured plastic flow stress of lead crystals under these conditions is shown to be field dependent and to be related to the thermal conductivity via the previously developed relation (σH − σS) = −AT ln (κH/κS).
