Abstract

Antiferromagnetic (AFM) materials have potential advantages for spintronics due to their robustness, ultrafast dynamics, and magnetotransport effects. However, the missing spontaneous polarization and magnetization hinders the efficient utilization of electronic spin in these AFM materials. Here, we propose a simple way to produce spin-splitting in AFM materials by making the magnetic atoms with opposite spin polarization locating in the different environment (surrounding atomic arrangement), which does not necessarily require the presence of spin-orbital coupling (SOC). We confirm our proposal by four different types of two-dimensional (2D) AFM materials within the first-principles calculations. Our works provide a intuitional design principle to find or produce spin-splitting in AFM materials.
