摘要：

The quadrupolar and dipolar magnetic phases in polycrystalline DyPd3S4 have been investigated by neutron scattering and muon spin rotation/relaxation (muSR) technique. The transition from paramagnetic to antiferroquadrupolar state at T-Q=3.4 K as well as two successive dipolar magnetic phase transitions at T(N1)approximate to1 K and T(N2)approximate to0.8 K are evidenced by anomalies in the observed relaxation rates in the zero-field muSR measurements. In addition, measurements in longitudinal external magnetic field showed clear evidence for field-induced dipolar magnetic moments below T-Q. In inelastic neutron scattering measurements the transition to an ordered lattice of the Dy quadrupole moments at T-Q is observed by a temperature dependent splitting of the ground-state crystal-field multiplet below T-Q. Neutron diffraction revealed the induced magnetic structure in the quadrupolar phase of DyPd3S4 to be of the canted antiferromagnetic type with a canting angle close to perpendicular, similar to the spontaneous zero-field magnetic structures below 1 K.
