Bubbles, on the other hand, are internally static cylindrical magnetic domains, stabilized by external fields and magnetostatic interactions. In its original theory, the droplet was described as an imminently collapsing bubble stabilized by spin transfer torque and, in its zero-frequency limit, as equivalent to a bubble. Without nanoscale lateral confinement, pinning, or an external applied field, such a nanobubble is unstable, and should collapse. Here, we show that we can freeze dynamic droplets into static nanobubbles by decreasing the magnetic field. While the bubble has virtually the same resistance as the droplet, all sigNature communicationsFreezing and thawing magnetic droplet solitons.PMC907237305K18EYA2017-067112019-04229Mohseni MChung SSchutz GKhademi MGoering EAkerman JGroß FBykova IMazraati HJiang SKhymyn RFrisk AWeigand MAwad AAAhlberg MGrafe JLe QTfalseFreezing and thawing magnetic droplet solitons.Magnetic droplets are non-topological magnetodynamical solitons displaying a wide range of complex dynamic phenomena with potential for microwave signal generation.
