In this work we present magneto-optical Kerr effect study of magnetization processes in amorphous glass - coated microwire of composition Fe_{77.5}Si_{7.5}B_{15}. Unique results obtained from microwire were compared to results of similar measurements on polycrystalline ribbon Co_2FeSi. In both cases reversal of longitudinal and transversal component of surface magnetization was studied. There was just a small variation in total change of magnetization caused by change in the direction of magnetic field in case of square hysteresis loops measured on microwire. However, switching field was angularly dependent and the change was considerably high and well predictable. The last two facts make such microwires outstanding candidates for sensors of magnetic field direction or spatial orientation.
