Crystal and electronic structure and magnetic properties of CeRhPb

Abstract

The new intermetallic cerium compound CeRhPb was synthesised by arc melting and studied by means of X-ray diffraction and magnetic measurements. The crystal structure determined from the single crystal X-ray data is of the ZrNiAl type (space group P 6 2m). The compound was found to be a Pauli paramagnet with 4f 0 ground state of the Ce atoms. The ab-initio band structure calculations performed without and with spin polarization confirmed nonmagnetic character of the plumbide studied.

New Quaternary Compounds R3Ni0.5SiS7 (R – Y, Sm, La) with the La3Mn0.5SiS7 Structure

“…The compounds exhibit non-linear optical properties due to noncentrosymmetric crystal structure. Functional materials based on this type of the compounds may be used as elements of modern devices [7].Among the large family of chalcogenides, rare earth-containing ones have much more complex electronic configuration compared to dand p-electron-containing chalcogenides, which in turn improves their thermoelectric, magnetic and optical characteristics [8,9].…”
