| Abstract: | The relation between the material interface of a magnetoresistive (MR) sensor and the stability of its response is investigated. The cause of the hysteresis in the response of an MR sensor to an applied field is investigated using numerical models (a micromagnetic slope model and a micromagnetic step model). Vortex formation is found in the MR sensor. This vortex formation is investigated further by means of an analytical method (Ginzburg–Landau model). |
