Controlling the domain wall dynamics in Co-rich magnetic microwires with graded magnetic anisotropy
Journal of Science: Advanced Materials and DevicesWe have shown after annealing Co-rich microwire in a temperature gradient, graded magnetic anisotropy is observed. In studied microwires annealed at variable temperatures, a gradual change in hysteresis loops along the length of the microwire from ...

Fast domain-wall propagation in uniaxial nanowires with transverse fields [PDF]
Physical Review B, 2013 Under a magnetic field along its axis, domain wall motion in a uniaxial nanowire is much slower than in the fully anisotropic case, typically by several orders of magnitude (the square of the dimensionless Gilbert damping parameter). However, with the addition of a magnetic field transverse to the wire, this behaviour is dramatically reversed; up to a ...

Quantum Dynamics of Spin Wave Propagation through Domain Walls [PDF]
Journal of the Physical Society of Japan, 2006 Through numerical solution of the time-dependent Schrodinger equation, we demonstrate that magnetic chains with uniaxial anisotropy support stable structures, separating ferromagnetic domains of opposite magnetization. These structures, domain walls in a quantum system, are shown to remain stable if they interact with a spin wave. We find that a domain

Development of Magnetic Microwires for Magnetic Sensor Applications
Sensors, 2019 Thin magnetic wires can present excellent soft magnetic properties (with coercivities up to 4 A/m), Giant Magneto-impedance effect, GMI, or rectangular hysteresis loops combined with quite fast domain wall, DW, propagation.

Actuators, 2021 A theory of voltage-induced control of magnetic domain walls propagating along the major axis of a magnetostrictive nanostrip, tightly coupled with a ceramic piezoelectric, is developed in the framework of the Landau–Lifshitz–Gilbert equation.

Journal of Science: Advanced Materials and DevicesUltrafast magnetization switching through the single domain wall (DW) propagation has been reported in amorphous micrometric and submicrometric wires. However the performance of prospective devices utilizing DW propagation is determined by the degree to ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We
