Skyrmion-antiskyrmion droplets in a chiral ferromagnet
Naveen Sisodia, Pranaba Kishor Muduli, Nikos Papanicolaou +1
We find numerically skyrmionic textures with skyrmion number Q=0 in ferromagnets with the Dzyaloshinskii-Moriya interaction and perpendicular anisotropy. These have the form of a s…
Traveling skyrmions in chiral antiferromagnets
Stavros Komineas, Nikos Papanicolaou
Skyrmions in antiferromagnetic (AFM) materials with the Dzyaloshinskii-Moriya (DM) interaction are expected to exist for essentially the same reasons as in DM ferromagnets (FM). It…
Skyrmion dynamics in chiral ferromagnets under spin-transfer torque
Stavros Komineas, Nikos Papanicolaou
We study the dynamics of skyrmions under spin-transfer torque in Dzyaloshinskii-Moriya materials with easy-axis anisotropy. In particular, we study the motion of a topological skyr…
Skyrmion dynamics in chiral ferromagnets
Stavros Komineas, Nikos Papanicolaou
We study the dynamics of skyrmions in Dzyaloshinskii-Moriya materials with easy-axis anisotropy. An important link between topology and dynamics is established through the construc…
Magnetic excitations in the spin-1 anisotropic antiferromagnet
C. Psaroudaki, S. A. Zvyagin, J. Krzystek +3
The spin-1 anisotropic antiferromagnet NiCl_2-4SC(NH2)_2 exhibits a field-induced quantum phase transition that is formally analogous to Bose-Einstein condensation. Here we present…
Precessing vortices and antivortices in ferromagnetic elements
Andreas Lyberatos, Stavros Komineas, Nikos Papanicolaou
A micromagnetic numerical study of the precessional motion of the vortex and antivortex states in soft ferromagnetic circular nanodots is presented using Landau-Lifshitz-Gilbert dy…
