Abstract
We report the observation of an unexpected phase transition at high magnetic fields between the spin-flop and spin-flip transitions in the d-electron antiferromagnetic metal V5S8. High-precision magnetic, thermal and electrical transport measurements enable the transitions to be tracked up to fields as high as 35 T and at temperatures down to the milli-kelvin range revealing three distinct magnetic quantum phase transitions. We present a model that finds agreement with our observation of a triad of spin transitions involving two sublattices with frustrated inter-and intra-sublattice spin couplings.
