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…
Nonreciprocal spin-charge interconversion in topological insulator/ferromagnet heterostructures
Shuyuan Shi, Enlong Liu, Fanrui Hu +3
The process of spin-charge interconversion is critical in modern spintronics. Nonetheless, experiments conducted on a wide variety of magnetic heterostructures consistently report…
Magnon-mediated perpendicular magnetization switching by topological crystalline insulator SnTe with high spin Hall conductivity
Pengnan Zhao, Guoyi Shi, Wentian Lu +10
Magnons possess the ability to transport spin angular momentum in insulating magnetic materials, a characteristic that sets them apart from traditional electronics where power cons…
