The shape of the curves for open flux circuit before and after T/sub c//sup am/ has been explained taking into account the external and internal demagnetizing effects, respectively. For Finemet, an ...

For demagnetizing field strengths well below the coercivity, the reversible permeability parallel to the easy axis amounts to 1.03-1.05 and perpendicular to the easy axis to 1.12-1.17, depending on ...
