IR spectra of YIG and substituted garnet crystals are investigated. We measured the transmittance spectra of polycrystalline samples and of single-crystal powders in KBr pellet and the transmittance and specular reflectance of single crystal slices, polished on both sides. The spectra were measured with a PE-580A IR spectrophotometer. For the reflectance measurements, a Perkin-Elmer specular reflectance unit was used. The angle of incidence in the unit was 6. 5 degree .
