F. Vajda et E. Dellatorre, MODELING DELTA-M CURVES USING THE COMPLETE-MOVING-HYSTERESIS MODEL, IEEE transactions on magnetics, 31(3), 1995, pp. 1809-1812
Using the complete-moving-hysteresis model it is shown that DELTAm cur
ves do not give a direct indication of the type of interaction but rat
her a combination of effects. An experimental analysis of commercial r
ecording media shows that the model accurately computes various types
of observed DELTAm curves. It is shown that the measured asymmetry in
DELTAm curves can be attributed the reversible component of the magnet
ization.
