摘要：

The magnetic and electric transport properties of the orthorhombic CeRhGa compound have been determined from the analysis of magnetic susceptibility, magnetization vs magnetic field, specific heat and electrical resistivity. The atomic positions and the lattice parameters were refined from Rietveld analysis. From our thermodynamical studies, CeRhGa is paramagnetic compound with valence instability of the 4f shell of Ce. X-ray photoelectron spectroscopy (XPS) measurements also confirm a mixed valent character of Ce and strong onsite hybridization between 4f and conduction electron states in the band. Band structure calculations give nonmagnetic ground state for CeRhGa and a good agreement between the measured valence band XPS spectra and the calculated bands. (C) 2010 Elsevier B.V.
