HIGH-SPEED HIGH-SENSITIVE MAGNETOOPTIC MATERIALS FOR PROMISING CIVILIAN APPLICATIONS

Using new epitaxial growth technology we produced (R, Bi)(3)(Fe,Ga)501 2 wafers possessing unique combination of static magnetic, magnetoopti c (MO) and domain wall dynamic properties. New concept of numerous and promising applications of the developed materials is presented. These applications include: 1) High resolution localizator of magnetic axis for multipole magnets in nuclear accelerators with space accuracy bet ter than 10 mu m in the field gradient >0,5 T/m. 2) MO flaw detectors providing real time image of defects both in magnetic and nonmagnetic metal articles; 3) Set or devices for latent marking of arbitrary arti cles: 4) Highly reliable MO bank-note tester for operative definition of bills and securities; 5) High speed MO spatial light modulators; 6) MO nonmechanical system for light beam scanning.
