Classical Spins in Superconductors

Hiroyuki Shiba

Department of Physics, University of Tokyo, Tokyo

(Received April 12, 1968)

Abstract:

It is shown that there exists a localized excited state in the energy gap in a superconductor with a classical spin. At finite concentration localized excited states around classical spins form an “impurity band”. The process of growth of the "impurity band" and its effects on observable quantities are investigated.
