Abstract

Neutron powder diffraction experiments have been performed on CePd 3S4 as well as measurements of magnetic and transport properties on a single-crystalline sample. Magnetic susceptibility increases markedly below TC = 6.3 K and a spontaneous magnetization appears below TC. The logarithmic temperature dependence of electrical resistivity implies that CePd3S4 is classified into a Kondolattice compound whose Kondo temperature is comparable to TC. Magnetic susceptibility is analyzed satisfactorily with a crystalline electric field model that the 4f ground state of Ce3+ is the Γ8 quartet with the excited Γ7 doublet located at 630 K. The magnetic structure of CePd3S4 was determined to be a canted structure with a canting angle of 51°. Such a canted structure is a result of the ferromagnetic (FM) ordering and simultaneous [100]-type antiferroquadrupolar (AFQ) ordering at TC. The smaller magnetization values and an unexpectedly high TC can be explained by the simultaneous occurrence of AFQ and FM order.
