Heisenberg spins on an anisotropic triangular lattice: PdCrO<sub>2</sub> under uniaxial stress
Abstract When Heisenberg spins interact antiferromagnetically on a triangular lattice and nearest-neighbor interactions dominate, the ground state is 120° antiferromagnetism. In this work, we probe the response of this state to lifting the triangular symmetry, through investigation of the triangular antiferromagnet PdCrO 2 under uniaxial stress by neutron diffraction and …
