“…In this way a small helical anisotropy was induced. The deviation of the easy axis from circular direction was very small, but this still enabled the creation of a single domain wall between circular domains (with negligible axial component of magnetization) in the wire [4]. This wall was created by applying an inhomogeneous axial eld generated by Helmholtz coils connected in anti-parallel combination.…”

An experiment, measuring the changes of impedance in a magnetic wire, caused by the presence of a single domain wall was proposed. The results obtained from a magnetic wire with small helical anisotropy show that for lower frequencies (up to about 1 MHz), the presence of wall causes an increase in impedance, very probably due to the wall displacement. As frequency increases, the inuence of the wall presence on the magnetic state causes the impedance to decrease in adjacent domains. For frequencies close to 10 MHz this eect overcomes the eect of wall displacement.
