    Asymmetric giant magnetoimpedance effect created by micro magnets
    (Elsevier Science Bv, 2018) Atalay, S.; Izgi, T.; Buznikov, N. A.; Kolat, V. S.
    Asymmetric giant magnetoimpedance (AGMI) effect has been investigated in as-prepared and current annealed amorphous (Co0.9Fe0.05Ni0.05)(75)Si15B10 ribbons. Asymmetry was created by micro magnets. Different numbers of magnets were used and it was found that increasing number of magnet, the shift in AGMI curves increases. When two micro magnets were placed 1 cm away from the ends of ribbon, a distortion in two peak shape of the GMI curve was observed. At high frequency range, a linear change in the AGMI was observed for the current annealed sample. (C) 2018 Elsevier B.V. All rights reserved.

    Formation of asymmetric giant magnetoimpedance in amorphous ferromagnetic wires by micro magnets
    (Iop Publishing Ltd, 2018) Buznikov, N. A.; Atalay, S.
    Asymmetric giant magnetoimpedance (AGMI) was created using two micro magnets placed at 1 cm away from the ends of amorphous ferromagnetic non-magnetostrictive (Fe0.06Co0.94)(72.5)Si12.5B15 wire. At low frequencies, single-peak behaviour of the AGMI was observed, and the AGMI curves exhibited two-peak behaviour within high-frequency range. The asymmetry in the magnetization curves of amorphous wire with two micro magnets having the same orientation was found, the maximum of the GMI ratio at positive field region decreases from 515% to 356%, and the peak value at negative field region decreases from 513% to 261% at 1 MHz driving current frequency. A linear change in the AGMI curves was obtained, which could be of importance for magnetic sensor applications. Experimental results were qualitatively explained in the framework of a model for the AGMI response in amorphous wire taking into account effects of bias field induced by micro magnets.
