Biomedical applications of glass-coated microwires

Journal of Magnetism and Magnetic Materials, 2019
Abstract In the given contribution, two examples of applications of glass-coated microwires for biomedical sensing are shown. Firstly, application of microwires for contactless sensing of the intracranial temperature below titanium implants confirms the possibility to sense the temperature with sensitivity down to 0.01 °C.

Ferromagnetic glass-coated microwires for cell manipulation

Journal of Magnetism and Magnetic Materials, 2020
Abstract The application of magnetic nanoparticles allows labeling the cell for its manipulation via the external magnetic field. In this work, it is proposed to use glass-coated magnetic microwires as a magnetic pin system to create a strong and well-localized magnetic field at the end of such microwires.

Magnetostatic interaction of glass-coated magnetic microwires

Journal of Applied Physics, 2010
We report on tailoring the hysteresis loops of arrays containing Fe- and Co-rich microwires utilizing effects of magnetostatic coupling. The interacting wires of both types may produce a complex magnetic response and highly specific spectral characteristics. For Fe-rich microwires we observed step-wise hysteresis loops with a number of Barkhausen jumps

Magnetoelastic anisotropy distribution in glass-coated microwires

Journal of Materials Research, 1996
Amorphous microwires, obtained by the glass-coated melt-spinning method having diameters in the range of micrometers, can exhibit perfectly square (single and large Barkhausen jump) or quasi-anhysteretic hysteresis loops, depending on the easy magnetization direction determined by the intrinsic magnetoelastic anisotropy.

Interdomain wall in amorphous glass-coated microwires

Physical Review B, 2007
Amorphous glass-coated microwires display a core-shell-type magnetic structure, whose main components, the inner core and the outer shell, have been extensively studied. In this paper, the interdomain wall that separates these two main components of the core-shell structure is investigated.

Magnetocaloric effect in nanogranular glass coated microwires

physica status solidi (a), 2008
AbstractThermal dependences of the magnetic susceptibility of the glass‐coated microwires with compositions Fe3P and SnMn prepared by the Taylor–Ulitovski method have been determined. Direct measurements of the adiabatic temperature change revealed ΔTad of 0.04 K in the SnMn and ΔTad of 0.02 K in the Fe3P microwires on the field change of 12 kOe ...

Magnetoimpedance of a glass-coated amorphous microwire

Journal of Applied Physics, 2009
A maximum magnetoimpedance (∼66%) was observed at 5.2 MHz in a positive magnetostrictive glass-coated amorphous Co83.2Mn7.6Si5.8B3.3 microwire. Giant magnetoimpedance in this microwire was increased to 129% on short-duration heat treatment by passing four current pulses of amplitude of 100 mA and each of 12 s duration.

FMR study of amorphous Co68Mn7Si10B15 glass-coated microwires

physica status solidi (a), 2003
The magnetic properties of Co 68 Mn 7 Si 10 B 15 glass coated amorphous microwires of about 16.5 μm in diameter have been investigated from liquid helium up to room temperature by ferromagnetic resonance at 9.243 GHz. Based on the results of measurements both the magnetic anisotropy constants, the first arising from the stress at the interface between

Hopkinson effect in Co‐rich glass‐coated microwires

physica status solidi c, 2014
AbstractWe present studies of the temperature dependence of AC susceptibility, χ, and magnetization, M in few Fe‐Cr based microwires. We observed drastic increasing of the χ in vicinity of Curie temperature which we interpreted as the Hopkinson effect. Cr content drastically affects the Curie temperature of studied microwires.

Domain-wall dynamics in glass-coated magnetic microwires

Journal of Magnetism and Magnetic Materials, 2007
Glass-coated magnetic microwires with positive magnetostriction show peculiar domain structure that consists mostly of one large domain with magnetization-oriented axially. It was shown that small closure domains appear at the end of the microwire in order to decrease the stray fields. As a result of such domain structure, the magnetization reversal in
