We are investigating ferromagnetism at the limit of today's technology and beyond. Magnetic anisotropy, domain configuration and domain wall properties are considered in systems when film thickness and lateral dimensions shrink.
We also consider ways of controlling these magnetic parameters by structural modifications, which consist of well-defined steps and voids of geometrical or chemical origin, or of lithographically fabricated dots of various sizes and shapes. Using such an approach, we are acquiring a better understanding of technologically relevant magnetic devices that necessarily deviate from an ideally flat surface.
