The symmetry analysis and magnetic model of Dy[Fe(CN)6]·4D2O

Magnetic structure of Dy[Fe(CN)6]*4D2O was determined by means of neutron powder diffraction. The magnetic structure consists of Fe and Dy sublattices, which are coupled antiferromagnetically leading to overall ferrimagnetic ordering with the Curie temperature Tc = 3.7 K.

Zusammenfassung:	Magnetic structure of Dy[Fe(CN)6]*4D2O was determined by means of neutron powder diffraction. The magnetic structure consists of Fe and Dy sublattices, which are coupled antiferromagnetically leading to overall ferrimagnetic ordering with the Curie temperature Tc = 3.7 K. While for Fe-atoms the y-component of magnetic moment is large and the z-component is negligible, in the case of Dy-atoms the x-and the y-magnetic moment components are large and the arrangement of magnetic moments on Dy-sublattice is non-collinear. In this magnetic structure the y-components of magnetic moment on Dy and Fe atoms are anti-parallel. Our magnetic structure refinement yields the moment value of 11.06 muB for dysprosium and 1.61 muB for iron atoms.
