Abstract :
Computer simulation of multiple-bubble propagation in a Bloch line memory was conducted. The simulation was simplified by confining it to two dimensions, by varying spatial and time increments according to the rapidity of bubble motion, and by calculating the conductor field in advance; in this way, it was possible to perform the simulation on a microcomputer. Simultaneous propagation of two bubbles was found to be possible under a bias field of 30 Oe and driving current of 5 mA. Though the medium coercivity is not considered, the driving current required for a given driving frequency may be estimated.
