Amplification of spin waves by moving magnetic flux vortices in magnet-superconductor layered structure

A new spin wave amplification mechanism in the structure magnet-type II superconductor is proposed and theoretically investigated. The amplification results from magnetic flux motion due to ac and dc currents in the superconductor and takes place in the region of its electrical stability. The gain m...

Summary:A new spin wave amplification mechanism in the structure magnet-type II superconductor is proposed and theoretically investigated. The amplification results from magnetic flux motion due to ac and dc currents in the superconductor and takes place in the region of its electrical stability. The gain may reach 100 dB/cm.
