Credit: SciTechDaily.comUniversity of Wyoming scientists have established a new approach to control magnetic states in 2D products, appealing innovative improvements in calculating technology and energy efficiency.Imagine a future where computer systems can find out and make choices in ways that simulate human thinking, however at a speed and effectiveness that are orders of magnitude higher than the existing ability of computers.Breakthrough in Magnetic ControlA research study group at the University of Wyoming developed an ingenious method to control small magnetic states within ultrathin, two-dimensional (2D) van der Waals magnets– a process akin to how turning a light switch controls a bulb. By sending a small electrical present– called a tunneling present– through this sandwich, the instructions of the magnets orientation of the magnetic domains (around 100 nanometers in size) can be determined within the individual chromium triiodide layers, Tian says.Advancements in Magnetic Spin ControlSpecifically, “this tunneling current not only can control the changing direction between two stable spin states, but likewise controls and induces changing in between metastable spin states, called stochastic changing,” states ZhuangEn Fu, a graduate student in Tians research lab and now a postdoctoral fellow at the University of Maryland.”Reference: “Tunneling current-controlled spin states in few-layer van der Waals magnets” by ZhuangEn Fu, Piumi I.
