      abstract     = {Quantum spin liquids are exotic states of matter that form
                      when strongly frustrated magnetic interactions induce a
                      highly entangled quantum paramagnet far below the energy
                      scale of the magnetic interactions. Three-dimensional cases
                      are especially challenging due to the significant reduction
                      of the influence of quantum fluctuations. Here, we report
                      the magnetic characterization of K2Ni2(SO4)3 forming a
                      three-dimensional network of Ni2+ spins. Using density
                      functional theory calculations, we show that this network
                      consists of two interconnected spin-1 trillium lattices. In
                      the absence of a magnetic field, magnetization, specific
                      heat, neutron scattering, and muon spin relaxation
                      experiments demonstrate a highly correlated and dynamic
                      state, coexisting with a peculiar, very small static
                      component exhibiting a strongly renormalized moment. A
                      magnetic field B≳4  T diminishes the ordered component
                      and drives the system into a pure quantum spin liquid state.
                      This shows that a system of interconnected S=1 trillium
                      lattices exhibits a significantly elevated level of
                      geometrical frustration.},
