Interaction of a Néel-type skyrmion with a superconducting vortex

چکیده

Superconductor-ferromagnet heterostructures hosting vortices and skyrmions are new area of an interplay between superconductivity magnetism. We study interaction a Neel-type skyrmion Pearl vortex in thin due to stray fields. Surprisingly, we find that it can be energetically favorable for the situated at some nonzero distance from center skyrmion. The presence vortex-antivortex pair is found result increase radius. Our theory predicts spontaneous generation vortex-anti-vortex possible under conditions

Néel-type skyrmion lattice with confined orientation in the polar magnetic semiconductor GaV4S8.

Following the early prediction of the skyrmion lattice (SkL)--a periodic array of spin vortices--it has been observed recently in various magnetic crystals mostly with chiral structure. Although non-chiral but polar crystals with Cnv symmetry were identified as ideal SkL hosts in pioneering theoretical studies, this archetype of SkL has remained experimentally unexplored. Here, we report the di...

Characteristics of ferroelectric-ferroelastic domains in Néel-type skyrmion host GaV4S8

GaV4S8 is a multiferroic semiconductor hosting Néel-type magnetic skyrmions dressed with electric polarization. At Ts = 42 K, the compound undergoes a structural phase transition of weakly first-order, from a non-centrosymmetric cubic phase at high temperatures to a polar rhombohedral structure at low temperatures. Below Ts, ferroelectric domains are formed with the electric polarization pointi...

Superconducting Vortex with Antiferromagnetic Core

We show that a superconducting vortex in underdoped high Tc superconductors could have an antiferromagnetic core. This type of vortex configuration arises as a topological solution in the recently constructed SO(5) nonlinear s model and in Landau-Ginzburg theory with competing antiferromagnetic and superconducting order parameters. Experimental detection of this type of vortex by muon spin reso...
