DecoupAsymPowderMagLong¶
Description¶
The Decoupling of asymmetry in the ordered state of a powdered magnet fit function for longitudinal polarization can be written as:
where:
\(a\) - a scaling parameter for the overall asymmetry
\(B0\) - the characteristic field
\(A_z(b) = {\frac{3}{4}} - {\frac{1}{4b^2}} + {\frac{(b^2-1)^2}{8b^3}}log|{{\frac{b+1}{b-1}}}|\)
For a rotating asymmetry use DecoupAsymPowderMagRot .
Examples¶
An example of when this might be used is for examining field dependence of \(\mu\) SR signals in a polycrystalline magnet[1].
