The evolution of the coercivity Hc and the switching field distribution (SFD) of some commercial iron particles for magnetic recording with the packing density p is analyzed. For some samples the curves Hc vs. p show a maximum and the corresponding SFD vs. p plots have a minimum.

Abstract
The evolution of the coercivity Hc and the switching field distribution (SFD) of some commercial iron particles for magnetic recording with the packing density p is analyzed. For some samples the curves Hc vs. p show a maximum and the corresponding SFD vs. p plots have a minimum. This behavior is ascribed to the different role of the axial interactions and of the lateral interactions among the particles. The cases of positive and negative interactions are also discussed. © 1992.File in questo prodotto:
