DyTiFe_(11) compound is a ferromagnetic substance.It has tetragonal body-centered ThMn_(12)-typecrystallographic structure.At room temperature,the easy magnetization direction is the c-axis.A spinreorientation begins to appear at about 175K.The contribution of Fe sublattice to magnetocrystallineanisotropy was determined by experiments and that of Dy sublattice was obtained by using single ion modelcalculation.Results show that the spin reorientation arises from the competition of anisotropy between Fe andDy sublattices.
