New Kind of Magnetism Spotted in an Engineered Material
All the magnets you have ever interacted with, such as the tchotchkes stuck to your refrigerator door, are magnetic for the same reason. But what if there were another, stranger way to make a material magnetic? In 1966, the Japanese physicist Yosuke Nagaoka conceived of a type of magnetism produced by a seemingly unnatural dance

Magnetism helps electrons vanish in high-temp superconductors
The Fermi surface on the left shows the arrangement of electrons in a copper-oxide high temperature superconductor before the “critical point.” After the critical point, the Fermi surface on the right shows that most electrons vanish. Research by the Brad Ramshaw’s lab connects this disappearance with magnetism. Credit: Nature Physics (2022). DOI: 10.1038/s41567-022-01514-1 Superconductors—metals in…
