The shape anisotropy effect on the magnetization configuration and the switching behavior of a permalloy Ni 80Fr 20 Pac-man (PM) elements was investigated. The PM elements were of a thickness of 40 nm and the investigation was done by magnetic force microscopes. In an elongated PM type-I (EPM-I) (10%), the probability to form a vortex configuration at an as-patterned state was lower than a PM-I element (47%). It was found that the magnetization of a EPM-II element switches through a single-domain reversal. The results show that a PM element involving a vortex-driven switching process has a nonreproducible reversal.
