Electric field switching of the uniaxial magnetic anisotropy of an antiferromagnet
Xianzhe Chen, Xiaofeng Zhou, Ran Cheng +9
Electric field control of magnetic anisotropy in ferromagnets has been intensively pursued in spintronics to achieve efficient memory and computing devices with low energy consumpt…
Magnetic domain wall Skyrmions
Ran Cheng, Maxwell Li, Arjun Sapkota +7
It is well established that the spin-orbit interaction in heavy metal/ferromagnet heterostructures leads to a significant interfacial Dzyaloshinskii-Moriya Interaction (DMI) that m…
Interlayer Couplings Mediated by Antiferromagnetic Magnons
Ran Cheng, Di Xiao, Jian-Gang Zhu
Collinear antiferromagnets (AFs) support two degenerate magnon excitations carrying opposite spin polarizations, by which magnons can function as electrons in various spin-related…
Magnonic Spin-Transfer Torque in Ferromagnet/Antiferromagnet/Ferromagnet Trilayer
Ran Cheng, Di Xiao, Jian-Gang Zhu
In an antiferromagnet (AF) with uniaxial anisotropy, spin-up and spin-down magnons coexist and form an intrinsic degree of freedom resembling electrons. When polarized by an adjace…
Nonabelian magnonics in antiferromagnets
Matthew W. Daniels, Ran Cheng, Weichao Yu +2
We present a semiclassical formalism for antiferromagnetic (AFM) magnonics which promotes the central ingredient of spin wave chirality, encoded in a quantity called magnonic isosp…
