About this listen
Join us in this episode as we dive into groundbreaking research on terahertz-driven dynamical multiferroicity in SrTiO₃, led by Stefano Bonetti and his esteemed collaborators from institutions like Stockholm University, SLAC, and NORDITA.
They explore how resonantly driving soft phonon modes with terahertz electric fields induces room-temperature magnetization in SrTiO₃—something that could revolutionize magnetic switches and ultrafast lattice control! Discover how circularly polarized fields generate a net magnetic moment through coherent ionic motion, paving the way for new advances in quantum materials and high-speed magnetic devices.
Tune in to explore:
- The dynamics of non-magnetic systems gaining magnetic properties
- The Barnett effect and its role in this novel phenomenon
- Exciting implications for ultrafast switching technologies in condensed matter physics.
Don't miss this captivating exploration of how light-driven lattice vibrations can generate magnetic order at the atomic scale!
