Abstract
The switching field for isolated gamma-Fe2O3 magnetic particles has be en investigated as a function of the applied field angle both experime ntally and numerically. Micromagnetic simulations for a typical measur ed particle with cubic crystalline directions of < 100 > and < 110 > w ith respect to its long axis were compared directly with experimental results, At large applied field angles, the agreement between experime ntal results and numerical simulations was poor, However, at the small er applied field angles the simulations gave reasonable agreement with the experimental results.
