- Magnetic Materials
Prof. Ross' research is directed towards the magnetic properties of thin films and small structures, particularly for data storage and logic applications, and towards methods for creating nanoscale structures based on directed self-assembly and lithography. Current research on magnetic materials includes the synthesis and characterization of magnetic nanostructures for domain wall logic devices, the behavior of 360 degree domain walls, magnetic metallic particles formed by templated dewetting, magnetoelasticity, magnetic perovskites such as Fe- and Co-substituted strontium titanate, magnetooptical materials for integrated optical isolators, and self-assembled oxide nanocomposites. Ross also studies the self-assembly of block copolymers and develops methods for templating self-assembly in order to form well-organized structures useful in nanoscale fabrication and devices. The Thin Film Laboratory includes a pulsed laser deposition system and an ultra-high vacuum sputter system, in addition to a range of magnetic, magnetooptical, and magnetoelectronic characterization equipment.
