| Volume 12, Issue 4 October - December 2022 | | Advertisement Physical Review X (PRX) just published the second in the recently debuted series of PRX Perspectives, offering forward-looking viewpoints of selected research topics or fields.
In this Perspective, Libor Šmejkal and Jairo Sinova, Institut für Physic, Johannes Gutenberg Universitat Mainz, along with Tomas Jungwirth, University of Nottingham, introduce altermagnetism as a new fundamental class of magnetism that stands shoulder to shoulder with the familiar ferromagnetism and antiferromagnetism in the century-old field of magnetism. With their unique insights and well-informed imagination, the three authors paint an exciting research landscape for this emerging area. Many topics in condensed matter physics, including spintronics, spin-caloritronics, and superconductivity, feature prominently in that landscape. Read the Perspective » | | | | |
