Structural properties and electronic structure of some ternary d-electron and f-electron intermetallics

We report on structural measurements on and electronic structure investigat ions of the alloyed compounds ZrNiSn, TiNiSn, CeNiSn and CeRhSb. We present measurements of lattice parameters as a function of temperature and analys is of a(T) and its relation to chi T, chi being the magnetic susceptibility . We observed a linear dependence of a(T) versus chi T for Zr, Ti and Ce al loys (for orthorhombic Cc alloys, the lattice parameters a, b and c scale l inearly with chi T). The x-ray photoelectron and ultraviolet photoemission spectra are further compared to the density of states, obtained from band-s tructure calculations.
