High-speed stroboscopic analysis of a current-drive magnetic-domain propagating circuit

A high-speed optical stroboscopic system has been employed to examine the motion of magnetic domains in a current-drive propagating circuit used in conjunction with yttrium orthoferrite. Effects due to variations in the drive and bias fields and the frequency of propagation are observed in various p...

Zusammenfassung:A high-speed optical stroboscopic system has been employed to examine the motion of magnetic domains in a current-drive propagating circuit used in conjunction with yttrium orthoferrite. Effects due to variations in the drive and bias fields and the frequency of propagation are observed in various parts of the circuit. The results are combined with the circuit and material parameters to yield a high-frequency propagation limit for the system and a qualitative understanding of the domain motion.
