Tuneable Composites Containing Magnetic Microwires

“…Negative magnetostriction coupled with tensile stress creates alternative left and right handed circular domains in the outer sheath of wires. Such domain configuration was observed in wires produced by various method including in-rotating water developed by Unitika LTD (Takajo at el, 1993) and in glass-coated microwires ( Chizhik et al, 2004;Chizhik et al, 2001). Such domain structure preserves even in wires with very small but negative magnetostriction (Vazquez et al, 2011;Zhukova et al, 2009;Chiriac & Ovari, 1996) and they demonstrate the highest sensitivity of GMI.…”

Modeling of magnetization reversal in amorphous wires

“…But the shape of the real curve is determined by the overcoming of the energetically barrier related to the To verify our modeling we used the results of Kerr microscopy experiments performed earlier in as-quenched Co 94 Fe 6 ) 72.5 Si 12.5 B 15 wires [2]. During these investigations the axial magnetic field has been directed along the wire axis, that is, perpendicular to the direction of circular surface anisotropy.…”

Magnetoimpedance and Field Sensitivity of CoFeSiB Amorphous Ribbons under Applied Tensile Stress

“…The magnetoimpedance (MI) effect consists of a large variation in real and imaginary components of impedance (Z) of a conductive magnetic specimen while high-frequency AC current flows through it and sample is subjected to DC magnetic field [1][2][3]. The MI ratio (MIR) is defined as…”
