Abstract
Magnetic bubble domains in epitaxially-grown magnetic garnet have been detected by the Hall effect of indium antimonide evaporated films. Several structures of propagating and detecting devices are compared. A propagating and detecting device stacked on a single substrate was fabricated. Devices having T-bar circuits with an 80- and a 40-μm period were tested for 15- and 10-μm bubbles, respectively; signal voltages of 1.2- and 1.4-mV peak were obtained, respectively. Noise voltage due to an interaction between propagating and detecting elements was observed, and a signal-to-noise ratio of 8-dB was obtained without cancelation of the noise voltage.Keywords
