Switching behavior of small soft magnetic elements

Hysteretic properties of submicron-sized soft magnetic elements as they might be used in integrated field sensors are computed. A new 3D micromagnetic simulation program was used which requires only workstation computing power. Results are scrutinized using previously established techniques. The influence of object shape and size is investigated and related to experimental findings reported in the literature.
