Neutron diffraction studies on modulated Tb2Ni3Si5 single crystal

Abstract Pulsed-neutron diffraction measurements have been performed on the Tb 2 Ni 3 Si 5 single crystal. Two different reciprocal lattices appeared in the observed reciprocal planes. The observed magnetic reflections indicated that each lattice has each antiferromagnetic spin configuration that is described by the multi-propagation vector system.
