Fig. 8.6 Mössbauer spectra
of an α-Fe foil 4.2 K for
different applied fields, as
example of a ferromagnet.
The line is a calculation of
the pure field effect.

between the spins and the lattice—so-called spin-lattice-relaxations—to name only
a few. These time dependence of hyperfine interactions can strongly influence the
shape of the measured spectra, if the corresponding characteristic relaxation time τ R
is in the range of the characteristic time of the experiment. Each measuring method
has its own characteristic time window. This is the time during which measurement
is performed. In case of a bulk magnetization measurement this is in the range of
1 up to 100 s. Ac-susceptibility measurements are in the range of 1– 10
−4 s, and
