Single crystals of the DyMn2 compound were grown by the Czochralski method
from a levitated melt. The electrical resistivity exhibits a magnetic trans
ition at 40 K, a second transition at 25 K, a cubic temperature dependence
at low temperatures and a saturation effect above 250 K. The magnetization
in strong magnetic fields, and the DC and AC magnetic susceptibility measur
ed along the principal crystallographic directions show an ordering of the
dysprosium moments to a spin-canted magnetic structure at about 40 K and a
spin reorientation below 25 K. The temperature dependence of the lattice pa
rameter shows a lattice contraction below 40 K. (C) 2000 Elsevier Science S
