Coupled quasimonopoles in chiral magnets
G. P. Müller, F. N. Rybakov, H. Jónsson +2
Magnetic singularities, also known as magnetic monopoles or Bloch points, represent intriguingphenomena in nanomagnetism. We show that a pair of coupled Bloch points may appear as…
Duplication, collapse and escape of magnetic skyrmions revealed using a systematic saddle point search method
Gideon P. Müller, Pavel F. Bessarab, Sergei M. Vlasov +5
Various transitions that a magnetic skyrmion can undergo are found in calculations using a method for climbing up the energy surface and converging onto first order saddle points.…
Lifetime of racetrack skyrmions
P. F. Bessarab, G. P. Müller, I. S. Lobanov +7
The skyrmion racetrack is a promising concept for future information technology. There, binary bits are carried by nanoscale spin swirls -- skyrmions -- driven along magnetic strip…
Method for finding mechanism and activation energy of magnetic transitions, applied to skyrmion and antivortex annihilation
Pavel F. Bessarab, Valery M. Uzdin, Hannes Jónsson
A method for finding minimum energy paths of transitions in magnetic systems is presented and used to determine the mechanism and estimate the activation energy of skyrmion and ant…
