YIG thin layers grown on (Y,Eu,Yb)$sub 3$(Fe,Ga)$sub 5$$O$$sub 12$ LPE films were found to be very effective for improvement of bubble propagation margin as well as for hard bubble suppression. In the ion-implanted rare earth substituted Ga:YIG on (111) GGG with 8 micron bubble, T-bar propagation margin was diminished, because of stretching or oscillating of bubble along the patterns. A 600 A YIG thin layer with in-plane magnetization, grown by CVD at 1065$sup 0$C, obviated these destructive shortcomings and guaranteed the minimum driving field for stable bubble propagation down to 10 Oe. This improvement can be attributed to the magnetostatic interaction between the YIG layer and the bubble supporting layer. (auth)
