Coexisting phases in triangular antiferromagnet- Livestream

Frustrated systems have energetic landscapes with many local minima and nearly degenerate states.This makes them ideal for exploring the competition and interactions between phases and their excitations at finite temperature. In iron-intercalated niobium disulfide, an antiferromagnet on a triangular lattice, two symmetry-breaking ordered ground states coexist in complicated ways, and give rise to low-power spintronic possibilities. This talk will discuss the evolution of these states in magnetic fields up to 60T, with the introduction of disorder, under applied strain, and upon current-based perturbations.
