      abstract     = {The triangular lattice with Ising magnetic moments is an
                      archetypical example of geometric frustration. In the case
                      of dipolar-coupled out-of-plane moments, the geometric
                      frustration results in a disordered classical spin-liquid
                      state at higher temperatures while the system is predicted
                      to transition to an anti-ferromagnetic stripe ground state
                      at low temperatures. In this work we fabricate artificial
                      triangular Ising spin systems without and with uniaxial
                      in-plane compression to tune the nature and temperature of
                      the correlations. We probe the energy scale and nature of
                      magnetic correlations by grazing-incidence small-angle
                      neutron scattering. In particular, we apply a
                      newly-developed empirical structure-factor model to describe
                      the measured short-range correlated spin-liquid state, and
                      find good agreement with theoretical predictions. We
                      demonstrate that grazing-incidence neutron scattering on our
                      high-quality samples, in conjunction with detailed modeling
                      of the scattering using the Distorted Wave Born
                      Approximation, can be used to experimentally quantify the
                      spin-liquid-like correlations in highly-frustrated
                      artificial spin systems.},
