Mossbauer study of the (Ru1-xFex)Sr2GdCu2O8-delta system and two of its possible impurities: SrRuO3 and Gd2CuO4
Mossbauer spectra of a series of samples of the weak ferromagnetic (Ru1-xFex) system reveal the existence of three dissimilar sites where the Fe atoms can go into the structure. The Mossbauer parameters of the three observed quadrupole doublets, together with the relative population on each site, al...

| Sumario: | Mossbauer spectra of a series of samples of the weak ferromagnetic (Ru1-xFex) system reveal the existence of three dissimilar sites where the Fe atoms can go into the structure. The Mossbauer parameters of the three observed quadrupole doublets, together with the relative population on each site, allow the following site assignment for the iron atoms: Fe3+ in four-fold planar coordination at Ru sites |
