Single-Conductor Magnetic-Bubble Propagation Circuits
John A. Copeland, J. P. Elward, William Arthur Johnson, J. G. Ruch · Journal of Applied Physics · 1971
Propagation circuits for circular magnetic domains using only a single electric current conductor are described. A circuit which in addition uses Permalloy dots for domain stability and for determining the direction of propagation has been operated at 475 kHz with a 100-mA amplitude current.
