Strain-tunable bipolarized Weyl semimetal and valley Hall effect in two-dimensional d-wave altermagnetic Fe2I2.
The discovery of altermagnetism, a novel magnetic order characterized by real-space antiferromagnetic alignment and reciprocal-space anisotropic spin polarization, has opened new avenues in spintronics and topological quantum materials. In this paper, we employ first-principles calculations to investigate the electroni...
