Reversible magnetic behavior in amorphous wires for precision sensing applications [PDF]

Scientific Reports
Amorphous magnetic wires based on Co-Fe alloys exhibit exceptionally soft magnetic behavior, making them attractive for advanced sensing technologies. Their magnetic performance is governed primarily by internal stresses, magnetoelastic interactions, and

Influence of the strain effect on magnetocrystalline anisotropy in Co2Fe0.4Mn0.6Si Heusler alloys [PDF]

Scientific Reports, 2023
The perpendicular magnetocrystalline anisotropy, magnetoelastic properties as well as the Gilbert damping factor in Co2Fe0.4Mn0.6Si thin films were found to depend on a magnetic layer thickness, and they can be also tuned by the application of additional

Manipulation of domain wall dynamics in amorphous microwires through the magnetoelastic anisotropy. [PDF]

Nanoscale Res Lett, 2012
We studied the effect of magnetoelastic anisotropy on domain wall (DW) dynamics and remagnetization process of magnetically bistable Fe-Co-rich microwires with metallic nucleus diameters (from 1.4 to 22 μm). We manipulated the magnetoelastic anisotropy applying the tensile stresses and changing the magnetostriction constant and strength of the internal

Structure–Property Relationships for Weak Ferromagnetic Perovskites

Magnetochemistry, 2021
Despite several decades of active experimental and theoretical studies of rare-earth orthoferrites, the mechanism of the formation of their specific magnetic, magnetoelastic, optical, and magneto-optical properties remains a subject of discussion.

Development of Co-Rich Microwires with Graded Magnetic Anisotropy

Sensors, 2021
In this paper, a gradual change in the hysteresis loop of Co-rich glass-coated microwire stress-annealed at variable temperature is observed. Such microwires annealed with a temperature gradient also present a variable squareness ratio and magnetic ...

Magnetoelastic anisotropy in NdFeB permanent magnets [PDF]

Journal of Applied Physics, 1999
The influence of magnetoelastic effects on the anisotropy in NdFeB permanent magnets has been investigated. A relation between the magnetostriction coefficients and the magnetoelastic anisotropy is derived for crystals with tetragonal symmetry. Transmission electron microscopy experiments show that stress and strain are present at the boundaries of the
