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…
Anomalous Feedback and Negative Domain Wall Resistance
Ran Cheng, Jian-Gang Zhu, Di Xiao
Magnetic induction can be regarded as a negative feedback effect, where the motive-force opposes the change of magnetic flux that generates the motive-force. In artificial electrom…
Dynamic Feedback in Ferromagnet/Spin Hall Metal Heterostructures
Ran Cheng, Jian-Gang Zhu, Di Xiao
In ferromagnet/normal metal heterostructures, spin pumping and spin-transfer torques are two reciprocal processes that occur concomitantly. Their interplay introduces a dynamic fee…
Antiferromagnetic Spin Wave Field-Effect Transistor
Ran Cheng, Matthew W. Daniels, Jian-Gang Zhu +1
In a collinear antiferromagnet with easy-axis anisotropy, symmetry dictates that the spin wave modes must be doubly degenerate. Theses two modes, distinguished by their opposite po…
Ultrafast Switching of Antiferromagnets via Spin-transfer Torque
Ran Cheng, Matthew W. Daniels, Jian-Gang Zhu +1
Picosecond switching of the staggered antiferromagnetic order is shown to be realizable through spin-transfer torques from a short current pulse. The coupled dynamics of sublattice…
