Interaction between Co-rich glass-covered microwires

Investigations on the magnetic reversal in a system of two glass-covered Co-rich amorphous microwires with circular bistability have been performed using the magneto-optical Kerr effect technique. The experimental configuration, when the electric current producing the circular magnetic field flows through the wires in opposite directions, has been employed first for the glass-covered microwires. The peculiarities of the obtained hysteresis loops reflect the influence of the axial stray fields produced by the Inner cores of the microwires on the circular magnetization reversal in the outer shells of the neighbouring microwires of the system. The experimental results have been analysed considering the mutual influence of microwires in the condition of the circular bistability effect.
