Néel‐Vector‐Dependent Unconventional Spin‐Orbit Torque for Deterministic Field‐Free Switching in NiO (110)‐Based Trilayers [PDF]
Advanced Science, EarlyView.Unconventional spin currents are generated in an antiferromagnetic NiO(110)/Ta/CoFeB trilayer, where the Néel vector governs spin transport. The resulting spin–orbit torques enable deterministic field‐free switching of perpendicular magnetization.

Micromagnetic simulations of magnetoelastic heterostructures [PDF]
, 2018 The system formed by a 10 nm thin film of Ni and a 10 μm-thick V2O3 layer shows a reversible enhancement of the coercivity (∼300%) due to the structural phase transition (metal/insulator) of the V2O3layer. Performing micromagnetic simulations and comparing the results with experimental data we have studied the coupling mechanism on the Ni/V2O3 ...

Two-dimensional overdamped simulations of droplet solitons activated by spin transfer torque
AIP Advances, 2020 We present overdamped micromagnetic simulations of the time evolution of magnetic droplet solitons which are formed in a thin film with perpendicular magnetic anisotropy by injecting a spin polarized current through a circular nanocontact. The overdamped

The role of grain size distribution on magnetic properties of sintered Nd–Fe–B magnets [PDF]
AIP AdvancesThe influence of grain size distribution for sintered Nd–Fe–B magnets is investigated using computational micromagnetics. The standard deviation of grain size distribution is selected as a quantity that can measure an inhomogeneity in grain size ...

Micromagnetic simulations of absoption spectra [PDF]
Journal of Magnetism and Magnetic Materials, 2006 Further development of a previously introduced method for numerically simulating magnetic spin waves is presented. Together with significant improvements in speed, the method now allows one to calculate the energy absorbed by the various modes excited by a position- and time-dependent H1 field in a ferromagnetic body of arbitrary shape in the presence ...

The stability of a skyrmion in a nanotube
New Journal of Physics, 2019 We study the stability of a skyrmion in a nanotube by using micromagnetic simulations. We find that skyrmions can exist stably in a nanotube within a moderate magnetic field range when the magnetic field is perpendicular to the center axis of the ...
