Micromagnetic modeling allows the systematic study of the effects of particle size and shape onthe first‐order reversal curve (FORC) magnetic hysteresis response for magnetite particles in the single‐domain(SD) and pseudo‐single domain (PSD) particle size range. The interpretation of FORCs, though widely used,has been highly subjective. Here, we use micromagnetics to model randomly oriented distributions of particlesto allow more physically meaningful interpretations. We show that one commonly found type of PSD particle—namely the single vortex (SV) particle—has far more complex signals than SD particles, with multiple peaksand troughs in the FORC distribution, where the peaks have higher switching fields for larger SV particles.Particles in the SD to SV transition zone have the lowest switching fields. Symmetrical and prolate particlesdisplay similar behavior, with distinctive peaks forming near the vertical axis of the FORC diagram. In contrast,highly oblate particles produce “butterfly” structures, suggesting that these are potentially diagnostic of particlemorphology. We also consider FORC diagrams for distributions of particle sizes and shapes and produce anonline application that users can use to build their own FORC distributions. There is good agreement betweenthe model predictions for distributions of particle sizes and shapes, and the published experimental literature.
