Join a 52-minute Physical Review Journal Club discussion where researchers I. Ardizzone, D. van der Marel, and M. Medarde present their findings on multiferroicity in rare earth nickelate single crystals. Explore Raman spectroscopy data revealing the multiferroic phase of R Ni O3 single crystals. Delve into topics including phase diagrams, magnetic structures, Raman shifts, and results for Ethereum and Crazyodemium Nickelates. Engage in a Q&A session addressing challenges, synthesis difficulties, and evidence for hexagonal phases, moderated by PRResearch co-lead editor Nicola Spaldin.
