An elusive massless particle could exist in a magnetic crystal structure, revealed by neutron and X-ray research. The team studied a material containing the dense element osmium and documented 2 conditions required for the presence of Weyl fermions -predicted in 1929 and observed experimentally in 2015. Researchers are looking for other materials that could host them to harness their unique properties in spintronics and advanced computing applications such as quantum computers.
“Once you have a material that hosts th...
