Frustration enhanced by Kitaev exchange in a ${\tilde{\mathbf{j}}}_{\text{eff}}=\frac{1}{2}$ triangular antiferromagnet

C. Wellm, W. Roscher, J. Zeisner +9

Triangular Heisenberg antiferromagnets are prototypes of geometric frustration, even if for nearest-neighbor interactions quantum fluctuations are not usually strong enough to dest…
