Abstract

Magnetization reversal processes in microstructured NLFe rings are studied by fringe-fieldinduced local Hall magnetometry. This semiconductor-based technique yields a high sensitivity of magnetic stray fields and allows us to detect magnetization hysteresis loops of single NLFe rings. The transition fields can be controlled by the ratio between inner- and outer-ring diameter. Comparison between Hall measurements and numerical simulation suggests that there are four different magnetization states in two integrated rings.
