Anisotropic spin filtering by an altermagnetic barrier in magnetic tunnel junctions
Boyuan Chi, Leina Jiang, Yu Zhu +3
The spin filtering effect, distinct decaying lengths experienced by oppositely spin-polarized electrons in a magnetic barrier, generally occurs in ferromagnetic (FM) insulators or…

Quantum-well resonances caused by partial confinement in MgO-based magnetic tunnel junctions
L. N. Jiang, B. Y. Chi, W. Z. Chen +1
Quantum-well resonance is achieved through partial confinement in magnetic tunnel junctions (MTJs), which provides an additional operable degree of freedom to regulate quantum-well…

Crystal facet orientated Altermagnets for detecting ferromagnetic and antiferromagnetic states by giant tunneling magnetoresistance effect
Boyuan Chi, Leina Jiang, Yu Zhu +4
Emerging altermagnetic materials with vanishing net magnetizations and unique band structures have been envisioned as an ideal electrode to design antiferromagnetic tunnel junction…
