MRS Bulletin Materials News Podcast · Sep 30, 2022 · 4m

In this podcast episode, MRS Bulletin’s Laura Leay interviews Sergey Artyukhin from the Istituto Italiano di Tecnologia and Louis Ponet, who is affiliated with both the Istituto Italiano di Tecnologia and Scuola Normale Superiore di Pisa about a topologically protected switching phenomena in ferroic materials. When a multiferroic crystal (GdMn2O5) is placed in a magnetic field at a very particular angle to a crystallographic axis, and the magnetic field is swept up and down twice, the system switches between four magnetic configurations. The interplay between the spin of the gadolinium and…
