Abstract
FIELD: cryogenic SHF microelectronics. SUBSTANCE: speed of movement of magnetic vortex lattice is one of key indicators of properties of superconductive material of type-II. Superconductor is subjected to action of spin wave with power 1.0-100.0 μWW and frequency in range 2-8 GHz, amplitude-frequency characteristic and phase-frequency characteristic of spin wave are measured, absorption frequency Fo of spin wave across magnetic vortex lattice is determined by amplitude-frequency characteristic. Speed Vo of propagation of spin wave on absorption frequency Fo is found by phase- frequency characteristic. Transport current with value from 0 to I of critical value is passed through superconductor, amplitude-frequency characteristic is measured and used to determine absorption frequency Foof spin wave across moving magnetic vortex lattice. Speed of movement of magnetic vortex lattice is determined by formula V= (F-F)V/F. EFFECT: increased accuracy of determination of speed of movement of magnetic vortex lattice, decreased cost of method.
