摘要：
Dynamical magnetic correlations in the geometrically frustrated Nd3Ga5SiO14 compound were probed by inelastic neutron scattering on a single crystal. A scattering signal with a ring shape distribution in reciprocal space and unprecedented dispersive features was discovered. Comparison with calculated static magnetic scattering from models of correlated spins suggests that the observed phase is a spin liquid inherent to an antiferromagnetic kagome-like lattice of anisotropic Nd moments.
