Magnetization is here normalized to the magnetization Mc
of a strip with uniform current density equal to jc.
Distinctions:
- For strong creep the merging of the virgin and the return branches
is somewhat delayed.
- Decrease of M with increasing applied field is much more pronounced for
strong creep. Note that this decrease is not due to jc(B)-dependence
since in both cases jc is assumed field-independent.
