Fluctuation driven phases in the triangular lattice — •P. Peter Stavropoulos¹, Roser Valentí¹, and Johannes Knolle² — ¹Goethe University, Frankfurt, Germany — ²Technical University of Munich, Garching, Germany

The triangular lattice has proven to be a model platform of frustrated magnetism, with a rich landscape of emergent phases. It is also an experimentally accessible platform, with many family of materials showing quasi-2D triangular arrangements of magnetic ions. Motivated by this, we revisit magnetic exchange models on the triangular lattice. We discuss phases that are stabilized by order by disorder mechanisms, and comment on their observable signatures.

Keywords: order by disorder; triangular lattice; fluctuation driven
