Abstract :
New single-crystal 6.3% SiFe wires with diameters of less than 90 ¿m and lengths of from 7 to 30 cm were produced by the R&D Division of Toyobo Ltd. Sensitive and complete bistable flux reversal (the large Barkhausen effect or re-entrant flux reversal), similar to that seen in amorphous magnetostrictive wires, was found to occur in these wire samples. Single-crystal 6.3% SiFe wire exhibits almost zero magnetostriction. The mechanism of domain wall propagation along the wire axis is analyzed. Pulse generation characteristics measured for various magnetic fields and stresses are described.
