"Superscale and Nanoscale Magnetism''
Among the grand challenges in nanoscience and nanomagnetism are: quantum understanding of spin-polarized matter at the 1-10 nm scale; complexity in fabrication and integration of top-down and self-assembled nanomagnetic structures; ultra-high-density information storage; nanomagnetic basis for magnetologic, spintronic and spin-qubit devices; ultra-strong permanent magnets; and ultra-small biomagnetic and other sensors. This talk will give an overview of critical issues in several of these topics, where fabrication of novel structures can lead to new properties and future applications. Exchange-coupled nanostructures for high-energy magnets and ultra-high density data storage will be discussed, as well as nanocluster magnetism in dilute magnetic oxides.
