“…However, when the dc magnetic field is applied perpendicular to the main axis, it is interesting to found that the GMI curve of NFCFCFN laminate shows an unusual single peak instead of typical double peaks [7][8][9][10][11][12][13][14][15]29] during either increasing or decreasing branch (shown as figure 4(b)).…”

“…In this study, we propose an alternative logic-in-memory device based on the improved asymmetric and hysteretic giant magnetoimpedance (GMI) effect of a magnetic heterostructure for the first time. For the GMI effect, the electrical impedance of a ferromagnetic conductor usually varies with the external dc magnetic field due to the varying magnetic permeability, which has attracted intense interest due to applications at the sensitive magnetic sensor [7][8][9]. The GMI effect of soft magnetic material usually varies nonlinearly and symmetrically near zero fields [7][8][9], which is inconvenient for obtaining the proper signal and determining the magnetic field direction for the magnetic sensor.…”

Hence, recently, various researchers have studied the asymmetric (and usually hysteretic) GMI effects to realize the auto-biased magnetic sensor.…”

The biphase magnetic heterostructure (Ni/Fe20Ni45Co25Si2B8/micro-planarcoil/Fe20Ni45Co25Si2B8/micro-planar coil/Fe20Ni45Co25Si2B8/Ni) bonded with a pair of thin magnets shows an improved asymmetric and hysteretic giant magnetoimpedance (GMI) effect with respect to an external dc magnetic field. This is attributed to the modification of the soft amorphous magnetic alloy’s (Fe20Ni45Co25Si2B8) permeability by the hysteretic magnetostrictive stress from the neighboring magnetostrictive Ni layer besides the magnetostatic coupling. More importantly, nonvolatile logic gates, such as NOR and NAND, can be implemented with either a single GMI laminate or arrays. On one hand, after applying two sequential magnetic field pulses as the logic inputs to a single proposed laminate, the nonvolatile output voltages are positive high (logic 1) or positive low (logic 0) depending on the signs and magnitudes of pulses. On the other hand, after applying the magnetic field pulses parallel to the GMI laminates arrays, different logic functions can be programmed and realized at run-time. The integration of memory and logic functions enables the proposed GMI laminate to be a possible candidate for future computing systems beyond von Neumann architecture.

“…This very good GFA of Co-based alloys allows different shape samples to be developed for research. As described above, the researchers were working on bulk metallic glasses (BMG) rods made using the copper mold injection casting method, but researchers also successfully obtained ribbons by melt spinning processes [ 22 , 23 ]. A more interesting shape, which was also studied in this work, is the powder form of an amorphous Co-based alloy.…”

Properties of Co-based alloys with high Glass Forming Ability (GFA) in the form of powder are still not widely known. However, powders of high GFA alloys are often used for the development of bulk metallic glasses by additive manufacturing. In this work Co47.6B21.9Fe20.4Si5.1Nb5% at. and Co42B26.5Fe20Ta5.5Si5Cu1% at. were developed by gas-atomization. Obtained powders in size 50–80 µm were annealed at Tg and Tx of each alloy. Then SEM observation, EDS analyses, differential thermal analysis, X-ray diffraction, nanoindentation, Mössbauer, and magnetic properties research was carried out for as-atomized and annealed states. The gas atomization method proved to be an efficient method for manufacturing Co-based metallic glasses. The obtained powder particles were spherical and chemically homogeneous. Annealing resulted in an increase of mechanical properties such as hardness and the elastic module of Co47.6B21.9Fe20.4Si5.1Nb5% at and Co42B26.5Fe20Ta5.5Si5Cu1%, which was caused by crystallization. The magnetic study shows that Co47.6B21.9Fe20.4Si5.1Nb5 and Co42B26.5Fe20Ta5.5Si5Cu1 are soft magnetic and semi-hard magnetic materials, respectively.
