The critical diameter between single domain and multidomain in single crystal L 10 -FePt particles has been studied. The particles are fabricated by depositing FePt on MgO(100) at 1173 K and the diameter was ranged from a few to over a hundred nanometers by changing nominal deposition thickness in the range of 2-10 nm. Initial anomalous Hall effect (AHE) curves were measured for as-deposited state and demagnetized state with in-plane field. The critical diameter for single domain obtained by analyzing initial curves coincides for both initial states and dc ∼55 nm for nominal thickness of 10 nm.
