Electronic and magnetic properties of pristine and lanthanide element doped yttrium iron garnet

ORAL

Abstract

The rare-earth based iron garnets (RIGs) have attracted significant attraction because of their wide technological applications such as in microwaves, optics, acoustics, magneto-optics, lasers, data storage, spintronics, and potentially in quantum information devices. In order to realize their potential applications, atomic-level details of the electronic, magnetic, intrinsic defect, and doping behavior in those materials need to be understood. Using first-principles electronic structure calculations, we investigate these properties in yttrium iron garnet (YIG). In addition, the role of lanthanide element doping in YIG and its impact on magnetic exchange interactions and defect states is explored. Moreover, incorporation of the lanthanide ions in YIG can potentially provide the defects with long spin coherence and stable optical transition.
