✦ Synopsis

A new series of oxynitrides LaVO~ xN, (0 < x < O. 9) has been synthesized and their electrical and magnetic properties studied. Contrary to the oxides' involving the mixed valence Vm-VI~; no semiconductor-metal transition is observed and all the compounds remain p-type semiconductors.

Oxynitrides of the general composition SrMoO 3Àx N x (x41) were synthesized by thermal ammonolysis of crystalline SrMoO 4 . According to neutron and X-ray diffraction experiments, the materials crystallize in the cubic perovskite structure (space group Pm3 ¯m). X-ray absorption spectroscopy (XAS) sh
