Abstract

Abstract : Multiferroic Materials In article number 2109144, Jae Hoon Kim, Je‐Geun Park, and co‐workers report a new exciton in multiferroic NiI2, consisting of a 2D triangular lattice. This newly discovered exciton is not only magnetic but also quantum entangled. When an electron and hole combine via a transition between two quantum‐entangled states, it produces a bright reddish light of 1.384 eV.
