Abstract

Measurements of S-state stability during translational motion show that bubble wall states in 5-6-μm YSmCaGeFeO films are stable at drive gradients more than double that in YEuGaFeO films. The increased stability is believed to result from greater damping and exchange energy in the YSmCaGe garnet.
