Energy-efficient spin Hall nano-oscillators using near-compensated CoGd ferrimagnets
Jiayu Lei, Raghav Sharma, Shishun Zhao +5
Conventional spin Hall nano-oscillators (SHNOs) based on ferromagnets face practical limitations due to high threshold current densities and large external magnetic field requireme…
Harnessing orbital Hall effect for energy-efficient magnetization switching in room-temperature van der Waals ferromagnet Fe3GaTe2
Chenhui Zhang, Hua Bai, Yuchen Pu +1
2D van der Waals (vdW) magnets provide new opportunities for spin-orbit torque magnetoresistive random-access memory (SOT-MRAM) due to their unique properties. Electrically manipul…
Electrical manipulation and detection of perpendicular altermagnetic order via proximitized Dirac semimetal
Zhaohui Li, Wenqing He, Hua Bai +14
Altermagnets, which combine antiferromagnetic-like magnetic compensation with ferromagnetic-like broken time-reversal symmetry, hold great promise for high-density and ultrafast sp…
Crystalline-dependent magnon torques in all-sputtered Hf/Cr2O3/ferromagnet heterostructures
Yuchen Pu, Guoyi Shi, Chenhui Zhang +3
Electron motion in spin-orbit torque devices inevitably leads to the Joule heating issue. Magnon torques can potentially circumvent this issue, as it enables the transport of spin…
Observation of magnon torques mediated by orbital hybridization at the light metal/antiferromagnetic insulator interface
Yuchen Pu, Guoyi Shi, Hua Bai +5
Magnon torques, which can operate without involving moving electrons, could circumvent the Joule heating issue. In conventional magnon torque systems, the spin source layer with st…
