Abstract :
A liquid analog of a magnetic bubble domain shift register has been constructed, using ferrofluid and an immiscible liquid. Bubble sizes from 50 to 1000 microns have been observed, with propagation frequencies to 60 Hz and propagation velocities for 300 micron bubbles of up to 6 cm/ sec. Display applications for these phenomena are discussed.
