Magnetic Quadrupole Lens and Current-Induced Quadrupolar Dynamics of Antiskyrmion
Linfeng Du, Yang Liu, Peng Yan +1
We demonstrate that antiskyrmions can serve as magnetic quadrupole lenses that focus or defocus electric currents traversing them. We showcase the antiskyrmion core as a focal poin…
Instability of two-dimensional nonrelativistic altermagnets
Zhejunyu Jin, Peng Yan
Altermagnets (AMs) are collinear compensated magnets that exhibit momentum-dependent spin splitting without requiring a net magnetization. Since local magnetic moments and exchange…
Helical Magnon Frequency Comb in Synthetic Antiferromagnetic Skyrmion Lattices
Liu Xuejuan, Zheng Xingen, Li Zhixiong +5
Synthetic antiferromagnetic skyrmion lattices (SAF-SkLs), consisting of two ferromagnetic SkLs coupled antiferromagnetically with compensated magnetization, provide a promising pla…
Nonlinear Dynamics of Hopfion for Frequency Multiplication
Waleed I. Waseer, Yunshan Cao, Peng Yan
Hopfions, associated with higher-dimensional topology through the Hopf fibration, exhibit {exotic} features like {complex knot} and improved stability compared to skyrmions, enhanc…
Engineering nonlinear magnon scattering in artificial spin ice via vertex dipolar control
Waleed I. Waseer, Peng Yan
Artificial spin ice (ASI), composed of geometrically frustrated arrays of interacting nanoislands, provides a versatile platform for reprogrammable magnonic functionality. However,…
Oxidation-induced ultrafast spin-to-orbital conversion at heavy-metal interfaces
Xiaoxue Zeng, Tianyi Zhang, Yaokai Niu +6
Oxidation engineering provides a route to control orbital degrees of freedom, yet its role in spin-to-orbital conversion remains largely unexplored. Here, we report an efficient sp…
Arbitrary-genus dark soliton gases in the defocusing nonlinear Schrödinger hydrodynamics
Marco Bertola, Deng-Shan Wang, Peng Yan +1
The defocusing nonlinear Schrödinger hydrodynamics supports exact dark solitons under finite density boundary conditions. However, the dark soliton gas, an interacting ensemble of…
Spin Elasticity:A New Paradigm for Spintronics
Zhong-Chen Gao, Tianyi Zhang, Feifei Wang +3
Elasticity shapes our world. For centuries, it has been regarded as a property exclusive to ordinary matter. Here we uncover its hidden existence in the spin degree of freedom. We…
Spin Elasticity
Zhong-Chen Gao, Tianyi Zhang, Feifei Wang +3
Elasticity has long been regarded as a property exclusive to material media. Here we uncover its hidden existence in the spin degree of freedom. We introduce spin elasticity-an int…
Stimulated Magnonic Frequency Combs
Xueyu Guo, Tianci Gong, Guibin Lan +5
Magnonic frequency combs, characterized by a series of discrete frequency lines, have emerged as a promising frontier in magnon spintronics, with potential applications in advanced…
Current-driven nonlinear skyrmion dynamics in altermagnets
Yang Liu, Zhejunyu Jin, Jie Liu +1
The center of mass and helicity are two dynamic degrees of freedom of skyrmions. In this work, we study the current-driven skyrmion motion in frustrated altermagnets. Contrary to c…
Alignment-Dependent Gapless Chiral Split Magnons in Altermagnetic Domain Walls
Zhaozhuo Zeng, Zhejunyu Jin, Peng Yan
Altermagnets, an emerging class of magnetic materials, exhibit exotic chiral split magnons that are of great interest for both fundamental physics and spintronic applications. Howe…
