SUMMARY:ESE Guest Seminar - "Van der Waals Quantum Materials for Magnetism and Clean Energy"
DESCRIPTION:In recent years\, numerous magnetic van der Waals layered quantum materials have been reported\, including transition-metal halides\, transition-metal chalcogenides\, transition-metal phosphorus chalcogenides\, and metal oxy- and chalco-halides. Unlike 3D counterparts\, layered magnets can be easily and rapidly exfoliated to yield ultra-thin magnets\, providing unique opportunities for both fundamental physics and new technologies. Furthermore\, these materials enable unprecedented experimental access to the ground states\, fundamental excitations\, and magnon dynamics\, as they are highly susceptible to external stimuli. In this talk\, I will present and discuss our recent findings in tuning the magnetic properties of quasi-2D layered van der Waals quantum magnets by intercalation\, photoexcitation\, proton irradiation\, and by the application of pressure. If time permits\, I will briefly discuss our recent efforts in solving the problems related to energy materials by employing magnetometry and electron paramagnetic resonance spectroscopy. NSF\, NRC\, ACS PRF\, and DOE supported this work. \nSome recent publications from our group: \n\nDynamic signatures of spin-lattice coupling in the layered ferrimagnet Mn3Si2Te6\, npj Spintronics\, 3\, 1 (2025).\nSpin-phonon coupling and magnetic transition in an organic molecule intercalated Cr2Ge2Te6\, Nano Letters.\, 24\, 9169 (2024).\nProton-fluence dependent magnetic properties of exfoliable quasi-2D van der Waals Cr2Si2Te6 magnet\, Phys.: Condens.
