要約(英語): We observed the repeatability of changes in the magnetic domains of three types of amorphous ribbons. These ribbons were cut at their edges and annealed to control their domain structures. The domain change of the cut samples had good repeatability. Moreover, jitter noise in the fluxgate-sensor output for the amorphous ribbon decreased. A decrease in the magnetization-reversal jitter could be achieved through magnetic domain-structure control of the sensor core, which could improve the sensitivity of the fluxgate.
