Preserved Fulltext
Nano-structured samples of SnO 2 doped with Fe prepared by the sol-gel method were studied by the Perturbed Gamma-Gamma Angular Correlation (PAC) Spectroscopy using 111 In ( 111 Cd) probe nuclei as well as by 57 Fe Mössbauer spectroscopy. The samples were prepared from very pure metallic Sn and Fe. Carrier-free 111 In nuclei were introduced during the sol-gel process of sample preparation for PAC measurements. The PAC measurements were carried out after annealing the samples at different
