An international team of researchers (China, USA – Boston College, Princeton University, Lawrence Berkeley National Laboratory, Taiwan) arranged atoms on the surface of crystals in many different patterns on ferromagnet to explore the associated phenomena. The electrons hovering above their atoms aligned in a straight line, with two-fold symmetry ignoring the lattice symmetry. When a magnetic field was applied they could turn one line in any direction they chose rotating the line of electrons just by controlling the magnetic field around them. Anisotropy was 100 times more than what theory predicts. The findings open enormous possibilities for next-generation nanotechnologies and quantum computing…read more. TECHNICAL ARTICLE
Each pattern is created in the lab of Princeton Professor Zahid Hasan by a particular direction of the external magnetic field applied on the sample. (Image: M. Z. Hasan, Jia-Xin Yin, Songtian Sonia Zhang, Princeton University)
