Crossover from diffusive to superfluid transport in frustrated magnets

We investigate the spin transport across magnetic phase diagram of a frustrated antiferromagnetic insulator and uncover drastic modification regime from diffusion to superfluidity. Adopting triangular lattice accounting for both nearest-neighbor next-nearest-neighbor exchange interactions with easy-plane anisotropy, we perform atomistic simulations on two-terminal configuration full diagram. found that as long ground state moments remain in-plane, irrespective whether is ferromagnetic, collinear, or noncollinear antiferromagnetic, system exhibits superfluid behavior device output independent value interactions. When frustration large enough compete anisotropy cant out plane, progressively evolves towards diffusive regime. The robustness superfluidity close boundaries investigated possibility proximate ferromagnetic transition.
