Lett.128, 111602 (2026); arXiv:2510.22153(2025) Deping Guo*, Weihan Zhang, Canbo Zong, Cong Wang, Wei Ji Abstract: Luttinger compensated antiferromagnets (LcAFMs), combining spin polarization with vanishing net magnetization, offer distinct advantages for next-generation spintronic applications. Using first-principles calculations, we demonstrate that conventional antiferromagnetic CrCl2 double chains can be transformed into one-dimensional LcAFMs under an external electric [&#8230;]]]></description>
