Losing 1 electron switches magnetism on in dichromium

The scientists used the unique Nanocluster Trap experimental station at the BESSY II synchrotron radiation source at Helmholtz-Zentrum Berlin and published their results in the Journal Angewandte Chemie.

Blocking infinity in a topological insulator

(Phys.org)—In bulk, topological insulators (TIs) are good insulators, but on their surface they act as metals, with a twist: the spin and direction of electrons moving across the surface of a TI are locked together. TIs ...

Exposing valence-bond model inadequacies

(Phys.org) -- Nature makes science fun by never failing to surprise. Just when scientists think they have a thing figured out, nature sends them scurrying to the whiteboard because of some unexpected result.
