LOW MAGNETIC SATURATION GARNETS.
Abstract
The anisotropy field measured on selected compounds of YCaVIG increased in a linear fashion with decreasing temperature. The room temperature anisotropy fields for YCaVIG materials are considerably higher than the BiCaVIG compounds for an equivalent 4(pi)Ms (at 4(pi)Ms of 530 gauss, 240 oersteds compared to 65 oersteds). Linewidth versus temperature measured for single crystals of YIG, BiCaVIG and BiCaV(Al)IG showed the linewidth to be independent of temperature from -60 to +60C. Remanence ratios (RR) of 0.55 with coercive fields of 3 oersteds were measured on single phase, high density Bi0.4Ca2.6V1.3Fe3.7O12. Materials containing a second phase of Fe2O3 showed a sharp drop in RR(0.55 to 0.38). The operation of a microstrip circulator using BiCaV(Al)IG material is described. (Author)
