Illustration of Kerr effect used to detect magnetization through the rotation of polarized light when it interacts with electron spins in a material. Shown are layers of chromium germanium telluride (CGT). The orange balls represent tellurium atoms, yellow is germanium, and blue is chromium. Credit: Zhenglu Li/Berkeley Lab

Study reveals unprecedented control of ferromagnetic behavior in 2D material. The scientists found that a 2D van der Waals crystal, part of a class of material whose atomically thin layers can be peeled off one by one with adhesive tape, possessed an intrinsic ferromagnetism.The discovery could have major implications for a wide range of applications that rely upon ferromagnetic materials, such as nanoscale memory, spintronic devices, and magnetic sensors...
