Amorphous magnetic metals are being investigated because of their outstanding magnetic behavior that makes them especially suitable as sensing elements in various devices [1]. Their particular magnetic behavior is a consequence of the intrinsic atomic disordering that in addition results in very interesting fundamental phenomena. Glassy metals are prepared by rapid solidification techniques that enable their preparation in planar (ribbons or thin films [2]) or cylindrical (wires) shapes [3]. Alternatively, amorphous alloys with interesting magnetic behavior can be also obtained as bulk material or can give rise to ultrasoft magnetic alloys after

“…These properties make multilayer microwires very suitable for several applications as elements in field, stress or temperature sensor devices [22], orthogonal flux-gates [23,24], biomedical applications [25], or microactuators [26]. For an overall information about the state of the art and applications, the reader is addressed elsewhere [27,28].…”

“…Because of complexity of the anisotropy, there are many metastable states of the magnetization, thus, the ordering is sensitive to initial conditions and external factors. On the other hand, the tube is a very important geometry among magnetic nano-and micro-systems since tubular coverings enable modifications of magnetotransport; GMI effect, and magneto-optical properties of wires and fibers to be utilized for sensing applications [1,2,3]. Also, magnetic microtube can serve as a sensing pipe for magnetic nanofluids [4].…”

Magnetization of soft-ferromagnetic nano-and microtubes of nanometer-thin walls (a single-widening rolled-up nanomembranes) is theoretically studied using analytical and numerical approaches including different stress-induced anisotropies. Within the analytical study, we consider magnetostatic effects qualitatively, with an effective anisotropy, while they are fully treated in the micromagnetic simulations (limited to the tubes of submicrometer diameters however). Basic types of the periodic ordering have been established and their presence in nanotubes of polycrystalline Permalloy and cobalt has been verified within the simulations. The domain structure is basically determined by a material-deposition-induced helical stress or a cooling-induced axial stress via the volume magnetostriction while it is influenced by the distribution of magnetic charges as well. Also, it is dependent on the initial state of the magnetization process.

“…The deposition of nonmagnetic or magnetic materials (hard or soft) on the glasscoated amorphous wires leads to changes in the magnetic behavior of these materials due to the contribution of the nature of the deposited material and to the supplementary stresses induced by the deposited material [8]- [10].…”

Magnetic Properties of CoFeSiB/(Co, CoPtRh) Multilayer Microwires

et al. 2015

View full text Add to dashboard Cite

The magnetic and magneto-transport properties have been investigated in a family of multilayer glass-coated microwires with a soft CoFeSiB nucleus and magnetically harder Co and CoPtRh deposited outer layers. Their magnetic properties are mainly determined by the magnetic interactions between the magnetic phases, i.e. the magnetoelastic coupling generated by the supplementary mechanical stresses induced by the deposited layers and by the magnetostatic interactions between the soft magnetic inner core and hard magnetic deposited layers. The deposition of 900 nm thick hard magnetic layers (Co and CoPtRh) on the soft magnetic CoFeSiB glass-coated microwire leads to a bi-phase magnetic character. Isothermal annealing at 300°C for 1 hour of multilayer microwires determines a slight decrease of the coercive field, an increase in the relative magnetic permeability and to an increase in the magneto-impedance response, more significant for the CoFeSiB/Co multilayer microwires. The possibility to design the magnetic and magneto-transport properties through magnetic coupling and annealing makes these materials very competitive as functional sensing elements.
