Determination of magnetic structures of RE3Fe3Sb7 (RE = Pr, Nd) using powder neutron diffraction
The intermetallic compound Nd3Fe3Sb7 is composed of two magnetic sublattices within an Sb framework. One-dimensional strands of face sharing Fe octahedra and stacks of triangularly arranged Nd atoms propagate along c direction. Magnetization measurements indicate complex and highly temperature dependent antiferromagnetic behavior of those sublattices. For weak magnetic fields, conventional antiferromagnetic behavior disappears upon cooling below 55 K and samples display a magnetic moment antiparallel to the external field . This effect of negative magnetization even occurs by spontaneous polarization at zero field. The rare earth substitution (Pr and Sm) strongly alters magnetic properties of the compound. Elucidating the magnetic structure is indispensable to understand the complex magnetic properties by sublattice interaction of those compounds. Therefore, we propose thermal neutron powder diffraction for Nd3Fe3Sb7 and Pr3Fe3Sb7.
