Crystal structure of rare-earth Dy3B2C3O12 garnets
The magnetic ground states of two rare-earth garnets Dy3Sc2Ga3O12 and Dy3In2Ga3O12 have been studied by neutron powder diffraction (D1B@ILL) during the last ILL cycle. Both compounds order with a k=0 multi-axis antiferromagnetic structure. We wish therefore to carry out high-resolution neutron powder diffraction (HRNPD) at RT on those two compositions, to position oxygen atoms precisely and to evaluate the distribution of atoms on the different sites, and in particular the possible substitution of Dy3+ on the B site, occupied by Sc or In. Analysis of the HRNPD data will lead to a proper modelling of the crystal structure for both garnets, this being a prerequisite to estimate the value of the ordered Dy3+ moment accurately in the ordered magnetic state. Moreover, it will allow us also to construct a reasonable point charge starting model before fitting CEF excitations (beamtime has been allocated on Panther@ILL to study CEF excitations in June 2021).
