Abstract:
Functional magnetic nanomaterials, whose properties are fundamentally different from their bulk counterparts, have attracted a global interest owing to their prospective applications in advanced spintronics and nanomedicine. In this lecture, I will discuss fundamental aspects of nanomagnetism, properties of magnetic materials upon size reduction to the nanoscale, and recent advances in synthesis, characterization and applications of magnetic nanomaterials and their hybrid nanostructures. In particular, I will demonstrate how magnetic (iron oxide) nanoparticles can be effectively exploited for selective drug delivery, magnetic hyperthermia, and biodetection. Finally, I highlight our recent discovery of strong room-temperature ferromagnetism in transition metal dichalcogenide (VSe2) as the material is reduced from bulk (micro-size) to a single layer (less than nm). This is a new type of magnetic nanomaterial which has the potential to transform the field of van der Waals spintronics.
