A domain wall and spin supercurrent can coexist in magnets with easy-cone anisotropy owing to simultaneous spontaneous breaking of ${Z}_{2}$ and U(1) symmetries. Their interaction is theoretically investigated in quasi-one-dimensional ferromagnets within the Landau-Lifshitz-Gilbert phenomenology. Specifically, the spin supercurrent can exert the torque on a domain wall and thereby drive it. We also show, as a reciprocal phenomenon, a field-induced motion of a domain wall can generate spin… Expand

Dynamics of bimeron skyrmions in easy-plane magnets induced by a spin supercurrent
We theoretically study the interaction of an isolated bimeron skyrmion in quasi-two-dimensional easy-plane magnets with a surrounding spin superfluid associated with spontaneously broken U(1)Expand
Domain wall dynamics in easy-cone magnets
We theoretically and numerically investigate magnetic domain wall dynamics in a nanowire of easy-cone magnet. The easy-cone domain wall exhibits several distinguishing dynamic features in comparisonExpand
Intrinsic origin of interfacial second-order magnetic anisotropy in ferromagnet/normal metal heterostructures
Interfacial perpendicular magnetic anisotropy, which is characterized by first-order ( K 1 ) and second-order ( K 2 ) anisotropy, is the core phenomenon for nonvolatile magnetic devices. A sizable KExpand
Evolution of strong second-order magnetic anisotropy in Pt/Co/MgO trilayers by post-annealing
In this study, the first- (K1) and second-order (K2) magnetic anisotropies are investigated as a function of post-annealing temperature (Ta) in Pt/Co/MgO heterostructures. We find that both extrinsicExpand
