METHOD OF DETERMINATION OF PARAMETERS OF LATTICE OF MAGNETIC CURLS IN SUPERCONDUCTOR OF II GENERATION Russian patent published in 1994 - IPC

FIELD: cryogenic SHF microelectronics. SUBSTANCE: superconductor is subjected to action with spin wave having capacity of 1-100 μW and frequency changing within range of 2-8 GHz. Amplitude and phase-frequency characteristics of spin wave are taken off. Absorption frequency F_o of spin wave on lattice of magnetic curls is found by amplitude-frequency characteristics, boundaries of frequency range within which absorption of spin wave on frequency F_o takes place and carry-over of 360 deg phase occurs are measured by phase-frequency characteristic. Parameter of lattice is calculated from expression T=C·(F₂-F₁)/F_o·(F₂+F₁), where T is parameter of lattice of magnetic curls; F₁ and F₂ are boundaries of frequency range within which absorption of spin wave at frequency F_o takes place; C is velocity of light in vacuum. Method is realized with the use of measurement set having SHF analyzer, electromagnet with power supply source, tesla meter, recorder and pickup. EFFECT: enhanced authenticity of determination of parameter. 4 dwg
