Skyrmions in antiferromagnets: thermal stability and the effect of external field and impurities
Maria N. Potkina, Igor S. Lobanov, Hannes Jónsson +1
Calculations of skyrmions in antiferromagnets (AFMs) are presented, and their properties compared with skyrmions in corresponding ferromagnets (FMs). The rates of skyrmion collapse…
Toward room-temperature nanoscale skyrmions in ultrathin films
Anastasiia S. Varentcova, Stephan von Malottki, Maria N. Potkina +3
Breaking the dilemma between small size and room temperature stability is a necessary prerequisite for skyrmion-based information technology. Here we demonstrate by means of rate t…
Stability of Long-lived Antiskyrmions in Mn-Pt-Sn Material
M. N. Potkina, I. S. Lobanov, O. A. Tretiakov +2
The lifetime of antiskyrmions at room temperature in a Mn-Pt-Sn tetragonal Heusler material has been calculated using an atomic scale representation including nearly a million spin…
Energy surface and lifetime of magnetic skyrmions
Valery M. Uzdin, Maria N. Potkina, Igor S. Lobanov +2
The stability of skyrmions in various environments is estimated by analyzing the multidimensional surface describing the energy of the system as a function of the directions of the…
The effect of confinement and defects on the thermal stability of skyrmions
Valery M. Uzdin, Maria N. Potkina, Igor S. Lobanov +2
The stability of magnetic skyrmions against thermal fluctuations and external perturbations is investigated within the framework of harmonic transition state theory for magnetic de…
