Discovered in the past few years, altermagnets combine a particular type of momentum- and spin-dependent energy of the mobile electrons with zero net magnetization—a desirable combination for a range of future electronic applications. Now Tong Zhou of the Eastern Institute of Technology, Ningbo, China, and his colleagues have shown theoretically that altermagnetism can be acquired by a nonmagnetic material immediately adjacent to an altermagnet [1]. The effect could potentially make altermagnetic properties available in more materials.
