We report on the magnetic properties and structural investigation of a rare-earth chromium borate. This system is isostructural to the recently discussed multiferroic rare-earth iron borate GdFe3(BO3)4. Magnetic Raman scattering and susceptibility show evidence for antiferromagnetic correlations within the Fe chains and a complex phase diagram. Work supported by DFG and ESF-HFM.
