Abstract

Bubble propagation by the domain drag effect is studied as a function of bias field (Hb) in a GdCoAu amorphous film with pulse widths of 20, 40, and 50 ns and current densities in the 4×106 to 7×106 amp/cm2 range by pulsing currents directly through a stripline of amorphous material containing hexagonal arrays of bubbles. With 0<Hb<500 Oe the bubble velocity is largely independent of bias field remaining constant at a value of 65 m/sec; as the bias field is increased above 500 Oe the velocity decreases gradually through a minimum of 35 m/sec at 1100 Oe and then increases to 65 m/sec at Hb=1440 Oe.(AIP). © 1979, American Institute of Physics.
