High Speed High Sensitive Magnetooptic Materials for Promising Civilian Applications

Using new epitaxial growth technology we produced (R, Bi)3(Fe,Ga)5012 wafers possessing unique combination of static magnetic, magnetooptic (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 better than 10 µm 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 of devices for latent marking of arbitrary articles : 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
