Static magnetic properties
Amorphous ferromagnetic materials

Table 6 lists a number of magnetic properties measured under DC conditions for as-quenched and longitudinal field-annealed alloys (Z-type annealed alloys).

µ_{r max} corresponds to the maximum relative impedance permeability (B_m/H_m) for an excitation frequency of 50Hz; we give a few values for comparison.

H_c is the coercive field and the ratio B_r/B_s is the straightness (rectangularity) of the static cycle (B_r is the remanent induction).

The static hysteresis cycles of the various alloys are shown in Figures 1 and 2. Note the great variety in the shape of these cycles, depending on the heat treatment.
