Miniaturized double-wing ∆E-effect magnetic field sensors [PDF]

Scientific Reports
Magnetoelastic micro-electromechanical systems (MEMS) are integral elements of sensors, actuators, and other devices utilizing magnetostriction for their functionality. Their sensitivity typically scales with the saturation magnetostriction and inversely

Magnetoelastic effects and magnetic anisotropy in Ni2MnGa polycrystals

Journal of Applied Physics, 2001
Linear thermal expansion and magnetostriction measurements under a magnetic field up to 20 kOe, applied parallel and perpendicular to the measuring direction and in the temperature range of 10–300 K, have been performed on a Ni2MnGa polycrystal. The effects of zero-field cooling and field cooling on both the self-strain (H=0) and the magnetic-field ...

Magnetic anisotropy and magnetoelastic properties of Fe₁₀Ni₉₀ films [PDF]

Journal of Physics: Conference Series, 2019
Abstract This work is devoted to studying the effect of the thickness and type of the buffer sublayer on the magnetic anisotropy and the magnetoelastic properties of Fe10Ni90 films. It is established that the anisotropy of Fe films strongly depends on thickness, which can be associated with the influence of several mechanisms of ...

Magnetoelastic anisotropy drives localized magnetization reversal in 3D nanowire networks

Nanoscale
Magnetization reversal in three-dimensional nanowire networks is driven by highly localized magnetic states, arising from the interplay of exchange, dipolar interactions and magnetoelastic anisotropy, thereby challenging the prevailing understanding.

Interplay of magnetocrystalline and magnetoelastic anisotropy in epitaxialCo(101¯0)films [PDF]

With the goal of creating an in-plane (IP) uniaxial anisotropy system, we deposited a thickness series of epitaxial Co⁡(10⁢‾1⁢0) films grown on Si(110) substrates with Ag(110) and Cr(211) buffer layers by magnetron sputtering. However, quantifying the IP magnetic anisotropy using ferromagnetic resonance measurements revealed a much more complex ...

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 ...
