Inelastic neutron scattering reveals a temperature-dependent excitation continuum in K2Ni2(SO4)3 arising from quantum fluctuations on a hyper-trillium lattice of corner-sharing tetrahedra formed by dominant fourth- and fifth-neighbor exchanges.
Structural disorder in Dy2Zr2O7 melts the spin ice state of Dy2Ti2O7, producing dynamic antiferromagnetic correlations without residual entropy or glass-like freezing down to 40 mK.
