Abstract: DEVICE PROPERTIES OF HETEROEPITAXIAL GARENT FILMS EVIDENCING GROTH-INDUCED MAGNETIC ANISOTROPY INTENDED FOR USED IN MAGNETIC DEVICES PERFORMING THE FUNCTIONS OF STORAGE, SWITCHING LIGHT DEFLECTION, ETC., ARE IMPROVED BY ANNEALING FOR CRITICAL PERIODS OVER THE TEMPERATURE RANGE OF FROM ABOUT 1200*C. TO 1350*C.

Abstract: MAGNETIZATION VALUES FOR A VARIETY OF MAGNETIC GARNETS CONTAINING PARTIAL NONMAGNETIC SUBSTITUTIONAL IONS REPLACING IRON ARE ALTERED BY ANNEALING IN HYDROGEN-CONTAINING ATMOSPHERES. SUCH CHANGES WHICH MAY BE BROUGHT ABOUT IN PERIODS AS SHORT AS FIVE MINUTES OR LESS AT TEMPERATURES OF THE ORDER OF FROM 500*C TO 800*C. RESULT FROM THE TEMPERATURE DEPENDENCE OF SITE PREFERENCE OF SUCH NONMAGNETIC SUBSTITUTIONAL IONS. SUCH CHANGES MAY ACCOMPLISH A "TAILORING" OF THE GARNET MATERIAL FOR USE IN MAGNETIC SWITCHES AND MEMORIES.
