Multiferroic Magnon Spin-Torque Based Reconfigurable Logic-In-Memory
Yahong Chai, Yuhan Liang, Cancheng Xiao +19
Magnons, bosonic quasiparticles carrying angular momentum, can flow through insulators for information transmission with minimal power dissipation. However, it remains challenging…
Sagnac interferometry for high-sensitivity optical measurements of spin-orbit torque
Saba Karimeddiny, Thow Min Jerald Cham, Orion Smedley +2
Sagnac interferometry can provide a significant improvement in signal-to-noise ratio compared to conventional magnetic imaging based on the magneto-optical Kerr effect (MOKE). We s…
Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…
Exchange bias between van der Waals materials: tilted magnetic states and field-free spin-orbit-torque switching
Thow Min Jerald Cham, Reiley J. Dorrian, Xiyue S. Zhang +7
Magnetic van der Waals heterostructures provide a unique platform to study magnetism and spintronics device concepts in the two-dimensional limit. Here, we report studies of exchan…
Strong variation of spin-orbit torques with relative spin relaxation rates in ferrimagnets
Lijun Zhu, Daniel C Ralph
Spin-orbit torques (SOTs) have been widely understood as an interfacial transfer of spin that is independent of the bulk properties of the magnetic layer. Here, we report that SOTs…
Thermally-generated spin current in the topological insulator BiSe
Rakshit Jain, Max Stanley, Arnab Bose +6
We complete measurements of interconversions among the full triad of thermal gradients, charge currents, and spin currents in the topological insulator BiSe by quantifying…
