Magnetic properties of Co-Fe-Si-B microwires
In the paper the magneto-impedance effect in the Co68:15Fe4:35Si12:55B15 microwire with diameter of about
100 m is carefully studied. The measurements in close contact and contactless geometry were carried out in the
static field ranging from 0 to 6 kA/m and frequencies of the alternating field from 20 Hz to 2 MHz. It is shown that
the examined microwire shows high anisotropy of soft magnetic properties i.e. the circumferential permeability
is at least 7 times higher than the longitudinal one. Moreover, the microwire can be used as highly sensitive
magneto-impedance sensor working in contactless geometry especially at fields below 200 A/m[…
