Abstract

The magnetic properties of the compound (CePd3)8Ge have been studied by means of neutron diffraction and specific heat measurement at ambient pressure and also of measurements of susceptibility and electrical resistivity under hydrostatic pressure. The magnetic modulation vector, q, of the antiferromagnetic phase is {001} and the spin polarization is parallel to q. With increasing the applied pressure up to 6 GPa, the Néel temperature keeps increasing, which indicates a strongly localized nature of the 4f-electrons of the compound.
