Editorial: Altermagnetism—A New Punch Line of Fundamental Magnetism

Abstract

Non sunt multiplicanda entia sine necessitate, entities should not be multiplied without necessity. This observation made by the Franciscan monk John Punch in 1639 [1] still resonates with one of PRX's editorial philosophies: new terminology should only be introduced into papers when it advances understanding. Yet, the second Perspective article we have invited and are now publishing [2] seems to have done just the opposite. It introduces a new term into the century-old field of magnetism: "altermagnetism." PRX's authors and readers could rightly ask: Why make an exception here?
