Symmetry-Tunable Skyrmions and Merons in Magnetic Nanodisks via Spatially Engineered Anisotropy
X. D. Wang, J. F. Oliveira da Silva, Z. H. Tao +3
We demonstrate that spatially engineered magnetic anisotropy can stabilize skyrmion and meron spin textures in magnetic nanodisks even in the absence of Dzyaloshinskii-Moriya inter…
Reversible and irreversible dynamical topological transitions of magnetic Hopfions
S. Y. Lu, H. M. Dong, D. X. Yu +1
Magnetic Hopfions are three-dimensional (3D) topological solitons characterized by a nonzero Hopf invariant and offer a promising platform for 3D spintronics. While their static st…
Geometric symmetry and size-dependent skyrmion phase transitions in magnetic nanostructures
J. Y. Wang, C. X. Zhao, Y. F. Duan +1
We investigate the interplay of geometric symmetry, size, and external magnetic fields in regulating individual skyrmion states within magnetic nanostructures. By analyzing nanodis…
Ultrasensitive acoustic graphene plasmons in a graphene-transition metal dichalcogenide heterostructure: strong plasmon-phonon coupling and wavelength sensitivity enhanced by a metal screen
Ícaro R. Lavora, Z. H. Tao, H. M. Dongd +3
Acoustic plasmons in graphene exhibit strong confinement induced by a proximate metal surface and hybridize with phonons of transition metal dichalcogenides (TMDs) when these mater…
