Superconducting Spin Valves Based on Spiral Magnets

—Structures with spiral antiferromagnets are proposed as superconducting memory elements. The first structure consists of one superconducting layer and one magnetic layer with a spiral magnetization. The latter is a Josephson junction with spiral magnet as a weak link. The schematic diagram of switc...

Summary:—Structures with spiral antiferromagnets are proposed as superconducting memory elements. The first structure consists of one superconducting layer and one magnetic layer with a spiral magnetization. The latter is a Josephson junction with spiral magnet as a weak link. The schematic diagram of switching between logic states in proposed structures is described.
