abstract = {Spirals and helices are common motifs of long-range order
in magnetic solids, and they may also be organized into more
complex emergent structures such as magnetic skyrmions and
vortices. A new type of spiral state, the spiral
spin-liquid, in which spins fluctuate collectively as
spirals, has recently been predicted to exist. Here, using
neutron scattering techniques, we experimentally prove the
existence of a spiral spin-liquid in MnSc2S4 by directly
observing the ‘spiral surface’—a continuous surface of
spiral propagation vectors in reciprocal space. We elucidate
the multi-step ordering behaviour of the spiral spin-liquid,
and discover a vortex-like triple-q phase on application of
a magnetic field. Our results prove the effectiveness of the
J1–J2 Hamiltonian on the diamond lattice as a model for
the spiral spin-liquid state in MnSc2S4, and also
demonstrate a new way to realize a magnetic vortex lattice
through frustrated interactions.},
