Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. Rosa, Y. Xu, et al.
This groundbreaking research by Priscila Rosa and colleagues unveils the antiferromagnetic Zintl phase Eu₅In₂Sb₆, showcasing its unique insulating properties and a remarkable large negative magnetoresistance. Their findings not only suggest a topologically nontrivial semimetallic state but also indicate the potential of Zintl materials for clean magnetic narrow-gap semiconductors.
