WebThe recently discovered material Cs3Fe2Br9 contains Fe2Br9 bi-octahedra forming triangular layers with hexagonal stacking along the c axis. In contrast to isostructural Cr-based compounds, the zero-field ground state is not a nonmagnetic S = 0 singlet-dimer state. Instead, the Fe2Br9 bi-octahedra host semiclassical S = 5/2 Fe3+ spins with a ...
