| The potential relevance of the Ba3NbFe3Si2O14 langasite in the field of multiferroism was investigated. Interesting properties were expected, in particular in view of the frustrating stacking of its magnetic Fe3+ cations into triangular planes of triangle units. We hereafter report results of specific heat and magnetic measurements, Mo¨ ssbauer spectroscopy and neutron diffraction. A peculiar magnetic structure is found out at low temperature. The Fe3+ magnetic moments adopt a triangular 1201 configuration within each triangle, which is in-phase propagated in each triangular plane and is helically modulated from plane to plane |
