Spin-reorientation in DyGa

We have used neutron powder diffraction to determine the magnetic structure of DyGa. This compound crystallises in the orthorhombic CrB-type structure with the Cmcm space group (#63) and the magnetic structure comprises ferromagnetic order of the Dy sublattice along the c-axis below TC=115 K. Upon cooling below 25 K, the Dy magnetic moments cant away from the c-axis towards the a-axis. At 3 K, the Dy moment is 9.8(2) μB and the Dy magnetic moments point in the direction θ=22(2)°θ=22(2)°, ϕ=0°ϕ=0° relative to the c-axis.
