摘要
The magnetism of the kagome-based Weyl semi-metal \ce{Mn3Sn} is explored using neutron and x-ray scattering. A co-planar anti-chiral ${\textbf k}={\textbf 0}$ magnetic order develops below $T_{\mathrm{N}}$~=~445~K, with an ordered moment of 2.1(1)$\mu_{B}$/Mn and a correlation length exceeding 350~nm at $T=300$~K. For $T更多
