LARGE BARKHAUSEN EFFECT OF 6.3-PERCENT SIFE SINGLE-CRYSTAL WIRE

Sensitive and stable large Barkhausen effect was newly found for 4 - 8 % SiFe single crystal wires developed by Toyobo Co., R&D. New pulse generator elements are constituted using 6.3 % SiFe single crystal wire which has nearly zero magnetostriction (λ100). Pulse voltages are induced at a pick-up coil for applied ac field of more than about 0.2 Oe with frequencies 0.01 Hz to 10 kHz. High reliability of pulse generation characteristics was estimated against disturbance stresses for the 6.3 % SiFe single crystal wire. © 1990 IEEE
