An international collaboration led by Dr. Alessandro Stroppa (CNR-SPIN, Italy) and Prof. Qihang Liu (Southern University of Science and Technology, China), with researchers from the Korea Institute for Advanced Study, has achieved a groundbreaking advance in magnetoelectric materials.The team has discovered a novel phenomenon termed "Ferroelectric Switchable Altermagnetism," demonstrating for the first time the reversible electrical control of altermagnetic spin states through ferroelectric polarization switching. This fundamental breakthrough, published as an Editors' Suggestion in Physical Review Letters and featured in Physics, establishes a new mechanism for non-volatile electrical manipulation of magnetic order with the first theoretical demonstration of electrically tunable altermagnetic properties, and a transformative approach for developing fully voltage-controlled multiferroic devices.

Negli ultimi mesi, due interviste rilasciate alla giornalista Valentina Busiello (informazione.it) da Fabio Miletto Granozio, Direttore di SPIN, e da Mario Cuoco, responsabile della sede di Salerno, sono state dedicate a far meglio conoscere al grande pubblico alcune delle principali tematiche di ricerca di SPIN, rimarcando al tempo stesso l’impegno dell’Istituto nel campo della comunicazione della scienza.
