The compound ScMn6Ge6 (HfFe6Ge6-type, P6/mmm) orders antiferromagnetically below TN=516 K. Neutron powder diffraction at various temperatures 1.5–309 K shows the existence of two distinct magnetic ordering ranges described by the commensurate q1=(0

The magnetic structure of the tetragonal antiferromagnetic LuFe4Ge2 and YFe4Si2 compounds has been studied by high resolution neutron and X-ray diffraction above and below the magneto-elastic transition at TN, Tc=32 K and 76 K, respectively. Below TN

A noncollinear-ferromagnetic spin-glass-like state was observed in Tb55Co20Al25 bulk metallic glass due to the strong random magnetic anisotropy. Associated with this behavior, we observed a comparatively large magnetic entropy change (ΔSm is 9.75 J
