Structural, magnetic, and optical properties of orthoferrite thin films
… was used to create thin films of Ce-Fe-O and Y-Fe-O systems. Deposition temperature and ambient oxygen pressure were varied systematically between samples to determine which deposition conditions were most favorable to the formation of cerium/yttrium orthoferrite. The structure and …

Ligand Design For The Separation Of Rare Earth Elements
Rare earth elements (La-Lu, Sc, and Y) exhibit unique magnetic and optical properties that make them irreplaceable components of many technologies. Concerns over the rare earth supply chain have focused efforts toward recycling rare earths from end of life technology. Less than 1% of the rare earth …

THE SPINTERFACE PROBLEM: AB-INITIO STUDIES OF FE-PHTHLOCYANINE ON TRANTITION-METAL OXIDES.
At the interface between a transition-metal oxide and a metal-organic molecule, electrons form interesting hybrid electronic states that characterize what is commonly called an organic spinterface. The central idea of our study is the possibility of exciting a spin coherent wave inside the …

Functional 2D nanoparticle/polymer array : interfacial assembly, transfer, characterization, and coupling to photonic crystal cavities
We developed a universal, facile and robust method to prepare free-standing, ordered and patternable nanoparticle/polymer monolayer arrays by evaporation-induced self-assembly at a fluid interface. The ultra-thin monolayer nanoparticle/polymer arrays are sufficiently robust that they can be …

Structure–Property Relationships in Hybrid Crystalline Materials for Multifunctional Light–Matter Interactions
Light and matter can interact in powerful ways when the light is intense enough. This phenomenon, known as optical nonlinearity, is at the heart of modern technologies that generate new colors of light, process information at ultrafast speeds, and enable quantum communication. However, finding …
