On the relaxation time of interacting superparamagnetic nanoparticles and implications for magnetic fluid hyperthermia

open access: yesBeilstein Journal of Nanotechnology, 2019
A critical discussion on the presently available models for the relaxation time of magnetic nanoparticles approaching the superparamagnetic regime in the presence of interparticle dipolar interactions is considered.

Suppression of Magnetization Ringing After Domain Wall Collision Studied by Micromagnetic Simulation

open access: yes, 2008
Magnetization ringing following domain wall collision on a ferromagnetic nanowire has been investigated by micromagnetic simulation. Suppressed magnetization ringing is observed with the introduction of a small ribbon to the nanowire.

Large-scale micromagnetic simulation of Nd-Fe-B sintered magnets with Dy-rich shell structures

open access: yesAIP Advances, 2016
Large-scale micromagnetic simulations have been performed using the energy minimization method on a model with structural features similar to those of Dy grain boundary diffusion (GBD)-processed sintered magnets. Coercivity increases as a linear function
