Abstract

One of the most popular nuclear probes, ⁵⁷Fe is used for the investigation of orientations of hyperfine fields and also for the determination of other important properties. In particular, the orientation of iron magnetic moments can be unambiguously determined, including its signs. Experiments with polarized radiation are presented with regard to selected systems. Orientation of electric field gradient is used for acquiring information about the shape of the texture-free spectra. Applications on the analysis of iron-based superconductors are presented.

Keywords: Crystalline texture; Electric field gradient; Hyperfie magnetic fields; Magnetic texture; Mossbauer spectroscopy.
