Electrically Switchable van der Waals Magnon Valves
Guangyi Chen, Shaomian Qi, Jianqiao Liu +14
Van der Waals magnets have emerged as a fertile ground for the exploration of highly tunable spin physics and spin-related technology. Two-dimensional (2D) magnons in van der Waals…
Narrow waveguide based on ferroelectric domain wall
Gongzheng Chen, Jin Lan, Tai Min +1
Ferroelectric materials are spontaneous symmetry breaking systems characterized by ordered electric polarizations. Similar to its ferromagnetic counterpart, a ferroelectric domain…
Geometric magnonics with chiral magnetic domain walls
Jin Lan, Weichao Yu, Jiang Xiao
Spin wave, the collective excitation of magnetic order, is one of the fundamental angular momentum carriers in magnetic systems. Understanding the spin wave propagation in magnetic…
Skew scattering and side jump of spin wave across magnetic texture
Jin Lan, Jiang Xiao
Spin wave and magnetic texture are two elementary excitations in magnetic systems, and their interaction leads to rich magnetic phenomena. By describing the spin wave and the magne…
Bidirectional spin-wave-driven domain wall motion in antiferromagnetically coupled ferrimagnets
Se-Hyeok Oh, Se Kwon Kim, Jiang Xiao +1
We investigate ferrimagnetic domain wall dynamics induced by circularly polarized spin waves theoretically and numerically. We find that the direction of domain wall motion depends…
Manipulating spin wave polarization in synthetic antiferromagnet
Jin Lan, Weichao Yu, Jiang Xiao
Polarization is a key ingredient of all waves, including the electromagnetic wave, the acoustic wave, as well as the spin wave. Due to the fixed ferromagnetic order, the spin wave…
