Abstract
The growth of CoGa2O4 and ZnCr2O4 spine! single crystals by means of the chemical vapour transport technique using chlorine as a transport agent is reported here. A thermodynamical study of the CoGa2O4--Cl2 system has been performed in order to define the growth conditions, and structural investigations using X-ray diffraction are carried out. Moreover, the magnetic and electronic properties of the polycrystalline powdered samples were studied by means of magnetic susceptibility measurements, X-ray photoelectron spectroscopy and X-ray induced Auger spectroscopy.File in questo prodotto:
