Barium Hexaferrite Thin Films as a Scalable Magnetic-Insulator Platform for Proximity-Engineered Spintronics
Shyam Sundar Poriah, Sanjana D. S., Agrim Sharma +8
Rare-earth iron garnets, such as yttrium iron garnet (YIG) and thulium iron garnet (TmIG), are the benchmark magnetic insulators for spintronic and magnonic devices, but achieving…
Signatures of moiré intralayer biexcitons and exciton-phason coupling in WSe2/WS2 heterostructures
Ranju Dalal, Harsimran Singh, Rwik Dutta +6
Interactions among electronic and lattice degrees-of-freedom are foundational to various phases in condensed-matter physics, yet the dynamic interplay between excitonic and phononi…
