| Abstract: | Angle dependence of Mössbauer spectra parameters on angle δO between the ψ-rays wave vectork and the unit cellc-axis of single crystal YBa2(Cu0.98Fe0.02)3O7?y is studied at room temperature. The present results give more detailed information about the correct manner of spectra fitting and EFG tensor parameters in positions of Fe-atoms in 1-2-3 crystal matrix. |
