NRS time spectra (open circles) measured at saturation (H =875 mT) with for (a) THIN-IN, (b) THIN-IF, (c) THICK-IN, (d) THICK-IF samples and corresponding fits (solid lines).
Hysteresis loops obtained from the fitting of the NRS time spectra for the four samples before (black dots) and after (red triangles) field cooling. The magnetic field H is parallel to the photon wave vector and to Fe in plane direction.
NRS time spectra (open circles) measured with at saturation (curves labeled “s”) and close to the inversion (curves labeled “i”) for the four different samples. The corresponding fits are shown as solid lines.
Isomer shift (IS), quadrupole splitting(QS), hyperfine field (BHF), relative width of the hyperfine field distribution (ΔBHF/BHF), and relative weight (RW) of the different components derived from the fitting of the NRS time spectra for the four samples at saturation (H = 875 mT).
