Abstract :
Using the complete-moving-hysteresis model it is shown that Δm curves do not give a direct indication of the type of interaction but rather a combination of effects. An experimental analysis of commercial recording media shows that the model accurately computes various types of observed Δm curves. It is shown that the measured asymmetry in Δm curves can be attributed the reversible component of the magnetization
