Magnetic ordering phenomena in DyPd3S4

Abstract Elastic and inelastic neutron scattering has been employed to study the quadrupolar and dipolar ordering phenomena in DyPd 3 S 4 . At T Q =3.4 K the Dy quadrupole moments undergo a phase transition to an ordered lattice, reflected by a distinct change of the crystal-field level scheme observed by neutron spectroscopy. At T N1 ≈1 K a phase transition of the Dy dipole moments to a long-range canted antiferromagnetic state is observed, followed by a second magnetic phase transition at T N2 ≈0.75 K characterized by a change of the canting angle.
