abstract = {Localized electron spins can couple magnetically via the
Ruderman–Kittel–Kasuya–Yosida interaction even if
their wave functions lack direct overlap. Theory predicts
that spin–orbit scattering leads to a
Dzyaloshinskii–Moriya type enhancement of this indirect
exchange interaction, giving rise to chiral exchange terms.
Here we present a combined spin-polarized scanning tunneling
microscopy, angle-resolved photoemission, and density
functional theory study of MnO2 chains on Ir(100). Whereas
we find antiferromagnetic Mn–Mn coupling along the chain,
the inter-chain coupling across the non-magnetic Ir
substrate turns out to be chiral with a 120° rotation
between adjacent MnO2 chains. Calculations reveal that the
Dzyaloshinskii–Moriya interaction results in spin spirals
with a periodicity in agreement with experiment. Our
findings confirm the existence of indirect chiral magnetic
exchange, potentially giving rise to exotic phenomena, such
as chiral spin-liquid states in spin ice systems or the
emergence of new quasiparticles.},
