Abstract: The crystallographic and magnetic structures of the HfFe<subscript>6</subscript>Ge<subscript>6</subscript>-type compound Ho<subscript>0.5</subscript>Y<subscript>0.5</subscript>Mn<subscript>6</subscript>Sn<subscript>6</subscript> have been studied by powder neutron diffraction and <italic>in-situ</italic> Lorentz transmission electron microscopy. Besides the nonlinear thermal expansion of lattice parameters, an incommensurate conical spiral magnetic structure was determined in the temperature interval of 2–340 K. A spin reorientation transition has been observed from 50 to 300 K, where the alignment of the <italic>c</italic>-axis component of magnetic moments of the Ho sublattice and the Mn sublattice transfers from ferrimagnetic to ferromagnetic.
