The magnetic properties and thermal expansion of the single crystals of DyFe11Ti are investigated in the temperature range 4.2-800 K. Besides of the magnetic ordering at T = 550 K and spin reorientation of the "cone-axis" type at T = 220 K, another phase transition was found at T = 120 K. It is apparently connected with a noncollinearity of the Dy sublattice at low temperatures. The magnetic ordering and the spin reorientation are accompanied by large magnetostrictive deformations.
