split
and
levels. In other words, from a comparison of the measured M(H)
curve with curves calculated by means of Eq. (3.1.4) for various values of
one may
obtain an experimental value for the parameter
Alternatively, one can keep H constant
and vary the temperature. Subsequently, one can compare measured M(T) or
curves
with calculated curves (with
again as adjustable parameter) and obtain in this way an
