We have studied the complex magnetic ordering of the Dy sublattices in orthorhombic Dy3Ag4Sn4 by high-resolution neutron diffraction and Sn-119 Mossbauer spectroscopy. Magnetic ordering in this compound occurs over two transitions. At 16 K the Dy( 2d) site orders in a doubled commensurate antiferromagnetic structure described by a propagation...

Eu2In and Eu2Sn crystallize in the orthorhombic Co2Si-type structure (oP12, Pnma, No. 62) with In and Sn atoms occupying one 4c site and the Eu atoms filling two other 4c sites. Eu2In has a nearly ideal first-order magnetostructural transition (FOMT) at 55 K with a hysteresis of less than 0.1 K, a large entropy change and an adiabatic...
