However, the presence of dipolar fields in ferromagnets, which restricts the formation of ultrasmall topological textures3,6,8,9,12, and the deleterious skyrmion Hall effect, when skyrmions are driven by spin torques9,10,12, have thus far inhibited their practical implementation. Antiferromagnetic ...
Room-temperature skyrmions in ferromagnetic films and multilayers show promise for encoding information bits in new computing technologies. Despite recent progress, ferromagnetic order generates dipolar fields that prevent ultrasmall skyrmion sizes, and
The spin torques acting on an AFM skyrmion and AFM bimeron do not create a Magnus force. • Antiferromagnetic bimerons and skyrmions, can be displaced by spin-polarized current (SPC). • Topological objects interacting with lattice defects. Abstract Antiferromagnetic skyrmions and bimerons are...
We claim that the underlying physics for the $z = 3$ antiferromagnetic quantum criticality is the emergence of fermionized skyrmion excitations at low energies, which form a Fermi surface, referred as a skyrmion liquid, where the interplay between itinerant electrons and skyrmions is argued to ...

Magnetic bimeron is a topological spin texture with particle-like characteristics, which can exist in chiral magnets with in-plane magnetic anisotropy. The magnetic bimeron with topological charge of one can be regarded as a counterpart of the magnetic skyrmion in perpendicularly magnetized systems. ...
Evolution from Neel order to d-wave superconductivity in the high Tcuprates is described in terms of the skyrmion-like spin texture induced by the doped hole. The pseudogap phase, which is associated with preformed pairs, appears when th... T Morinari - 《Superconductor Science & Technology》...
We find that two distinct antiferromagnetic skyrmion crystal (AF-SkX) states can be stabilized at low temperatures in the presence of external magnetic field. The results are obtained via Monte Carlo simulations on an effective magnetic model derived from the microscopic electronic Hamiltonian consisting...
