Investigation of the crystal and magnetic structures of ScFe2Dx type compounds
From macroscopic magnetic measurements we have observed both a large change of the magnetization and huge unit cell expansion upon insertion of hydrogen/deuterium in ScFe2. Here we intend to investigate the ScFe2 type hydrides, determine the hydrogen location within the crystal and its effects on the crystal lattice distortion. We are also interested in the determination of the magnetic structure in order to know the magnetic moments magnitudes on the two inequivalent Fe atomic positions. A further aim is to investigate the effect of the local atomic environment on the magnitude of the magnetic moments of the Fe atoms. The study starting with ScFe2Dx will be extended to the Sc rich side of the (Sc,Nb)Fe2Dx compounds. The possible occurrence of a magnetic moment on the Sc position will also be investigated. We request for neutron diffraction experiments at 1.28A in order to explore a wider range of the reciprocal space and determine the crystal structure and experiments at 2.52A at low temperature to investigate the magnetic structure in a series of selected (Sc,Nb)Fe2Dx compounds for a total of 4 days on D1B instrument.
