摘要

Magnetic Barkhausen noise and hysteresis loops have been measured in the presence of various tensile stresses from three wire-shaped amorphous magnetic materials having different domain structures. Long duration large Barkhausen pulse indicates the presence of an inner core (IC) domain in positive magnetostrictive glass-coated Co83.2Mn7.6Si5.8B3.3 and Co58.59Fe4.41Ni10Si11B16 microwires where magnetization takes place by similar to 180 degrees. rotation of domain magnetization. This long duration Barkhausen pulse is missing in the case of low negative magnetostrictive Co68.1Fe4.4Si12.5B15 wire indicating a negligible volume of IC domain in it. Short duration pulses observed in all three samples suggest the presence of a multi-domain outer shell where small angle rotation and domain wall displacement are responsible for the magnetization process. The shapes of the hysteresis loops support the Barkhausen noise studies.
