abstract = {Topological semimetals in ferromagnetic materials have
attracted an enormous amount of attention due to potential
applications in spintronics. Using first-principles density
functional theory together with an effective lattice model,
here we present a new family of topological semimetals with
a fully spin-polarized nodal loop in alkaline metal
monochalcogenide MX (M = Li, Na, K, Rb, or Cs; X = S, Se, or
Te) monolayers. The half-metallic ferromagnetism can be
established in MX monolayers, in which one nodal loop formed
by two crossing bands with the same spin components is found
at the Fermi energy. This nodal loop half-metal survives
even when considering the spin–orbit coupling owing to the
symmetry protection provided by the Mz mirror plane. The
quantum anomalous Hall state and Weyl-like semimetal in this
system can be also achieved by rotating the spin from the
out-of-plane to the in-plane direction. The MX monolayers
hosting rich topological phases thus offer an excellent
platform for realizing advanced spintronic concepts.},
