The Faraday rotation and infrared studies of (Y3-yCe y)(Fe,Ga)5O12 (Ce=0 to 20% relative metal content) garnet films deposited on quartz and Gd3Ga5O12 (GGG) are reported. The value of θf reaches a maximum with Ce between 5 and 15%, depending on the heat pulse annealing temperature. The film crystallinity deposited on quartz, analyzed by X-ray diffraction and by sharpening of bands near 500 cm-1 in FTIR, reaches a maximum with Ce=5% and then decreases. Values of the Faraday rotation are related to the crystallinity of the deposited films
