Abstract
A magnetic structure for the propagation of magnetic bubbles at elevated velocity. A magnetic bubble layer is grown on a [110] face of a substrate, the lattice misfit being between -6.times.10.sup.-3 and -2.times.10.sup.-3, and the magnetic layer having a composition on the basis of europium-iron garnet and a damping parameter .ltoreq.3.times.10.sup.-7 Oe.sup.2 sec/rad.
