Abstract of Publication No. 565
Chirality is shown to emerge as a novel degree of freedom of a quantum
soliton in the anisotropic spin-1/2 compound CsCoBr3. The soliton chirality,
detected via polarized neutron scattering, is in agreement with
theoretical predictions and is a manifestation of Berry's phase.
Our observations provide an explicit example of the emergence of
spin currents and hidden chiral order that accompany the disappearance
of antiferromagnetic order.
