Structural and magnetic investigations of Fe 2 O 3 – TeO 2 glasses

A series of tellurite glasses containing Fe2O3 with the nominal composition x(Fe2O3)–(1 x)(TeO2), where x = 0.05, 0.10, 0.15, and 0.20, have been synthesized and investigated using X-ray photoelectron spectroscopy (XPS) and magnetization techniques. The Te3d core level spectra for all glass samples show symmetrical peaks at essentially the same binding… (More)
