Abstract :
Accurate evaluation of interactions in modern structured particulate ferromagnetic media is an actual problem of technological interest. In this paper, we present the results of a systematic study of perpendicular and longitudinal networks of Ising-type magnetic entities. We show the complex structure of interactions in such systems and their strong state dependence. The first-order reversal curves (FORC) diagram method in physical and operative planes is discussed. Even if the FORC diagram is only a picture of a moving distribution of interactions, in some cases the dynamic image of the interactions can be reconstructed from the static FORC diagram
