Abstract

A review of recent works on spin valves is presented. A number of CoO/Fe1/Cu/Fe2/S multilayers (S = In or Pb) are prepared and studied in detail. The full spin-valve effect for the superconducting current in these heterostructures is realized for the first time; its sign-changing oscillatory behavior is observed, depending on the thickness of the Fe2 layer; and direct evidence of long-range triplet superconductivity is found.
