Chiral nature of magnetic monopoles in artificial spin ice

New Journal of Physics, 2013
Micromagnetic properties of monopoles in artificial kagome spin ice systems are investigated using numerical simulations. We show that micromagnetics brings additional complexity into the physics of these monopoles that is, by essence, absent in spin ...

A skyrmion-based spin-torque nano-oscillator

New Journal of Physics, 2016
A model for a spin-torque nano-oscillator based on the self-sustained oscillation of a magnetic skyrmion is presented. The system involves a circular nanopillar geometry comprising an ultrathin film free magnetic layer with a strong Dzyaloshinkii–Moriya ...

Simulating micromagnetism

Advances in Physics: X
We present an introductory review of concepts behind micromagnetic simulations, in which magnetic moments representing collections of atomic spins within a material evolve according to the Landau-Lifshitz-Gilbert equation, a generalized torque equation.

Tunable domain wall pinning behavior by notch geometry in CoFeB nanostrip under nano-pulse current injection

Kuwait Journal of Science
To optimally control the domain wall (DW) pinning behavior in the ferromagnetic nanostrip, some focus is on utilizing a geometrical notch as an artificial pinning potential.

Manipulation of 2D and 3D Magnetic Solitons Under the Influence of DMI Gradients

IEEE Open Journal of Nanotechnology
Magnetic solitons hold great promise for token-based computing applications due to their intrinsic properties, including small size, topological stability, ultra-low power manipulation, and potentially ultra-fast operation.
