Measurement of a 1/2 magnetization plateau in a triangular antiferromagnet

ORAL

Abstract

Frustrated magnetic systems lend themselves to a wealth of nontrivial behaviors. Among these are plateaus in magnetization with the application of an external field, which can result from quantum fluctuations or a strong magnetocrystalline anisotropy. The existence of these plateaus at specific fractions of the saturated magnetization has been observed in a handful of systems with distinct physics. This talk will discuss our discovery of a ½ magnetization plateau in a frustrated antiferromagnet on a triangular lattice using fields up to 60T, as well as our minimal model, informed by ab initio calculations, that predicts this behavior.
