DecoupAsymPowderMagRot¶

Description¶

The Decoupling of asymmetry in the ordered state of a powdered magnet fit function for rotational asymmetry 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 longitudinal polarization use DecoupAsymPowderMagLong .

Examples¶

An example of when this might be used is for examining field dependence of :math:`mu`SR signals in a polycrystalline magnet[1].
