We present a study of crystalline structure, local environment around the magnetic atoms and magnetic behaviour of Fe 0.3 Ti 0.7 O 2-δ films, produced by Pulsed Laser Deposition, as a function of oxygen pressure and substrate temperature. Dark films

A mixed Fe,Cr oxide formed of maghemite and chromium hydrous oxide was prepared by oxidative precipitation at 90 °C. Mineral acids dissolve the chromium phase very quickly, whereas iron dissolves slowly and independently; there is little mutual infl

We report measurements on x-rays diffraction and Raman, infrared and Mossbauer absorption spectra of Bi2Sr2Ca1(Cu1−x, Fex)2O8+δ, 0·05≤x≤0·25. X-ray analysis shows that the increment of Fe in the CuO2 layers results in the growing of the n=1

XRD analysis and Mossbauer Spectroscopy studies were performed on samples of the ceramic oxide of nominal composition Bi2Sr2CaCu2O8 doped with iron substituting copper up to 25%. XRD results point out that increased doping favors the growth of the n=

Mossbauer spectroscopy spectra of the ceramic Bi2Sr2Ca(Cu1-x Fe x )2O8+y forx=0, 0.005, 0.02 and 0.05 shows two doublets, that can be assigned to two different environments for the substituting ion. One of the sites is identified as a single Fe ion r
