Valdez-Grijalva, Miguel A.; Muxworthy, Adrian R.; Williams, Wyn; O. Conbhui, Padraig; Nagy, Lesleis; Roberts, Andrew; Heslop, David

Description

First-order reversal curve (FORC) diagrams are used increasingly in geophysics for magnetic domain state identification. The domain state of a magnetic particle is highly sensitive to particle size, about which FORC diagrams provide valuable information. However, the FORC signal of particles with nonuniform magnetisations, which are the main carrier of natural remanent magnetisations in many systems, is still poorly understood. In this study, the properties of non-interacting, randomly oriented...[Show more]
