Characteristics of Temperature‐Stable Eu‐Based Garnet Films for Magnetic Bubble Applications

Epitaxial garnet films Y3−xEuxAlyFe5−y O12, with x=1.5–2.0 and y=0.7–1.2 and small additions of Yb, are reported: with 1–7‐μ bubbles; with bubble diameters that are relatively constant versus temperature; and in which bubble velocities greater than 1500 cm/sec have been observed. These materials show promise for bubble device applications.
