The paper discusses the achievement of valley polarization in twisted antiferromagnetic (AFM) systems by applying an out-of-plane electric field. Twisted magnetic van der Waals bilayers are identified as an ideal platform for achieving various types of altern magnetism, such as $d$-wave, $g$-wave, and $i$-wave, by selecting monolayers with specific symmetry. The authors propose that an out-of-plane electric field creates a layer-dependent electrostatic potential, causing the valleys from different layers to stagger and leading to valley polarization. This method is demonstrated using the twisted tight-binding model and verified through first-principles calculations on twisted bilayer VOBr and monolayer Ca(CoN)$_2$. The findings suggest that these materials can serve as promising candidates for innovative spintronics, twistronics, and valleytronics applications. The work highlights the potential of twisted AFM systems in multifunctional device applications, providing new opportunities for advanced electronic devices.The paper discusses the achievement of valley polarization in twisted antiferromagnetic (AFM) systems by applying an out-of-plane electric field.
