Surface magnetic properties of Co69Fe4Si15B12 when DC and AC currents flow through the ribbon

“…The transverse hysteresis loops of sample B measured with the electrical current flowing through the ribbons are shown in Fig 3. Similar hysteresis loops have been observed in Co 67 Fe 3:85 Ni 1:45 B 11:5 Si 14:5 Mo 1:7 glass-covered amorphous microwires [6] and they can be explained in the following way. In the case of the hysteresis loops in the absence of electric current when the longitudinal magnetic field decreases from 96:8 A m À1 there is a monotonic increase of the Kerr signal.…”

“…The surface magnetic properties of soft magnetic materials can be studied by magnetooptical Kerr effect (MOKE) [5,6]. In this work, we present the study of the surface magnetic properties and the magnetic domain structure of Co 69 Fe 4 Si 15 B 12 amorphous ribbons fabricated with or without application of the magnetic field during the solidification process and showing giant MI effect.…”

Investigation of magnetic structure in cold-drawn Fe-rich amorphous wire

“…Our paper is devoted to the investigation of the magnetic properties of Fe-rich amorphous wires prepared such as has been mentioned, having the initial diameter of around 0:125 mm to be reduced after cold-drawn process to 0:05 mm: The observation of the magnetoimpedance effect in the wires of this type [7][8][9] has defined our aspiration to observe and determine the magnetic structure of these wires. The joint application of magneto-optical Kerr effect [10] and fluxmetric methods provides the possibility to obtain interesting information about the different projection of the magnetization as a response to a combination of axial and circular magnetic fields. …”
