Localized Electron Nature of the Antiferromagnetism of (CePd_3)_8Ge : Response to Hydrostatic Pressure and Neutron Diffraction

概要

論文の詳細を見る
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} I and the spin polarization is parallel to q. With increasing the applied pressure up to 6 GPa, the Neel temperature keeps increasing, which indicates a strongly localized nature of the 4f-electrons of the compound.
