A groundbreaking achievement in the realm of quantum materials has been made by a research team from the High Magnetic Field Center of Hefei Institutes of Physical Science, Chinese Academy of Sciences. The team has successfully predicted a novel type of antiferromagnetic material, dubbed the "X-type antiferromagnet." This material boasts a distinctive cross-chain architecture and exhibits sublattice-selective spin transport properties, thereby offering capabilities unattainable with conventional magnetic materials. The significant findings of this research have been featured on the cover of Newton, a prestigious journal published by Cell Press. This discovery not only expands the repertoire of antiferromagnetic structures but also paves the way for more efficient information reading and writing in antiferromagnetic spintronic devices, along with the innovation of new device designs.
