Content overview: “Altermagnetism Confirmed: SLAC Scientists Prove Third Magnetic Phase with Geometric Twist”. For the first time, physicists have experimentally confirmed a third fundamental type of magnetism, known as altermagnetism, in a breakthrough published in Science. The discovery was led by researchers at the U.S. Department of Energy's SLAC National Accelerator Laboratory, who used a geometric twis Department of Energy's SLAC National Accelerator Laboratory, who used a geometric twist to provide conclusive evidence of this long-predicted magnetic phase.
Until now, only ferromagnetism and antiferromagnetism were recognized in materials without external influence. Altermagnetism combines properties of both, with zero net magnetization like antiferromagnets but with spin-split electronic bands like ferromagnets. This unique combination could enable faster, more efficient spintronic devices, which use electron spin rather than charge for information processing. The SLAC team's experimental proof opens the door to exploring altermagnetic materials for next-generation memory and logic technologies.
