blochLaw¶
- Stoner.analysis.fitting.models.magnetism.blochLaw(T, Ms, Tc)[source]¶
Bloch’s law for spontaneous magnetism at low temperatures.
- Parameters
T (array like) – Temperatures at which M has been measured (Probably in K)
Ms (float) – The magnetisation at 0K (in whtaever units M is being measured in)
Tc (float) – Curie temperature in K
- Returns
(array like) – Calculated values of M
Notes
This fits the Bloch Law as given by:
\(M(T) = M_s\left[1 - \left(\frac{T}{T_C}\right)^\frac{3}{2}\right]\)
This expression is only really valid in the low temperature regime.
