We have made magnetization measurements and neutron diffraction experiments on Y1-xDyxMn6Sn6 alloys with hp13 type (MgFe6Ge6 type) structure. The magnetization for the alloys reaches the saturation in a field around 13 T for x = 0, and around 5 T for x ≥ 0.4. The saturated magnetization decreases with increasing x. It is likely that the magnetic moments of Mn atom (μMn = 10μB/Mn atom) and Dy (μDy = 10 μB/Dy atom) are antiferromagnetically coupled to each other.
