Stephan Krohns,Peter Lunkenheimer,Ch. Kant,A. V. Pronin,H. B. Brom,Agustinus Agung Nugroho,Markus Diantoro,Alois Loidl +7 more
TL;DR: In this article, the dielectric properties of a charge-ordered nickelate, La15/8Sr1/8NiO4, surpass those of other materials.
Journal ArticleDOI
Multiferroicity in an organic charge-transfer salt that is suggestive of electric-dipole-driven magnetism
Peter Lunkenheimer,Jens Müller,Stephan Krohns,F. Schrettle,Alois Loidl,Benedikt Hartmann,Robert Rommel,Mariano de Souza,Mariano de Souza,Chisa Hotta,John A. Schlueter,Michael Lang +11 more
TL;DR: Evidence is provided for ferroelectricity, accompanied by antiferromagnetic spin order, in a two-dimensional organic charge-transfer salt, thus representing a new class of multiferroics, and a charge-order-driven mechanism leading to electronic ferroElectricity is proposed.
