You pretty much have it. You just need to force Mathematica to use
the local variable from the Manipulate. One easy way is to use
ReplaceAll to rename VolumeFraction to a temporary variable
(VolumeFraction2):
Manipulate[
LogLinearPlot[
Evaluate[
Re[MeasuredCMF] /. {VolumeFraction -> VolumeFraction2}], {f, 10^5,
10^9}],
{{VolumeFraction2, 0.2}, 0.1, 0.5}]
Good luck!
