(a) Variation of total asymmetry at \(t\sim 0 \, \mu \text {s}\) from the raw spectra. (b) Variation of internal field (\({\text {H}}_{\rm{int}}\)) with temperature. (c) Temperature variation of \(\lambda _0\) and corresponding asymmetry \({\text {A}}_0\) is shown as inset. Region (I), (II) and (III) are described using Eq. (7) with \(\sigma =0\), Eqs. (9) and  (7) respectively. (d) Temperature dependence of \(\lambda _1\) and the inset presents the variation of \({\text {A}}_1\).
