Please I want to know how Can I measure the saturation magnetization from the Mossbauer magnetic field data
Don't know whether there's an easy way to do this without heavy assumptions about what the actual hyperfine fields are (in relation to local moments).
However, if your sample is a thin film with the dominant magnetic anisotropy being shape anisotropy, then you know that your film saturates at Hext=Msat.
And with Fe (I suppose you're doing Mößbauer spectroscopy on Iron), with measurements in applied field, lines 2 & 5 of the sextett will disappear once the magnetization is fully aligned with the field. Putting these two things together, you can estimate Msat from observing the (relative) intensities of lines 2 & 5 as a function of applied field.
