In this research, magnetic anisotropy of Co_68.15Fe_4.33B_12.5Si₁₅ microwires were investigated. For this purpose, VVSM (Vector Vibrating Sample Magnetometer) analysis, which measures the transverse components of the magnetization simultaneously with the longitudinal one, was used. The magnetic field is applied in different directions with respect to cylindrical axis of wire and magnetization were recorded along X and Y direction. The component of magnetization along X direction decreases with increasing angle, while for Y component the magnetization increases with increasing angle of applied field. The results are explained in terms of unusual magnetic domain structure of wires.
