Measurement of a 1/2 magnetization plateau in a frustrated antiferromagnet*

Frustrated magnetic systems lend themselves to a wealth of nontrivial behaviors. Among these are plateaus in magnetization with the application of an external field, resulting from quantum fluctuations stabilizing particular spin states. 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 recent discovery of a ½ magnetization plateau in a frustrated antiferromagnet on a triangular lattice using fields up to 65T. This directly confirms recent theoretical predictions in frustrated magnets.
