Optical manipulation of magnetism holds promise for future ultrafast spintronics, especially with lanthanides and their huge, localized magnetic moments. These 4f moments interact indirectly by spin polarizing the conduction electrons (the Ruderman-Kittel-Kasuya-Yosida exchange interaction), influenced by interatomic orbital overlap, and the conduction electron's susceptibility around the Fermi level.

Platinum is important to many technological fields, and, in particular, it is often used as a catalyst. Many chemical reactions require high temperatures and/or pressures, rendering them energy-intensive. A promising approach to reduce this energy cost is to employ photocatalysis. One emerging approach is to employ bimetallic heterostructures that combine a catalytically active material (e.g., platinum or palladium) with a plasmonic material (e.g., silver, gold, or aluminum),11.
