Abstract

A fullyc-axis oriented thin film of YBa2(Cu0.9857Fe0.02)3O6.8 prepared by planar dcsputtering has been investigated by means of Mössbauer spectroscopy. Room temperature57Fe conversion electron Mössbauer spectra taken at different angles between the γ-ray direction and the normal (=c-axis) of the film show four subspectra: A (quadrupole splitting ΔEQ≈1.9 mm/s), B (ΔEQ≈1 mm/s), C (ΔEQ≈0.5 m/s) and D (ΔEQ≈1.6 mm/s). For subspectra A, B and C, we found the same hyperfine parameters as already published on other samples. The hyperfine parameters for subspectrum D are determined for the first time using a fully oriented sample. For D, we found the asymmetry parameterη ≥0.6 andVzz (the main component of the electric field gradient) lying in the a-b-plane.
