  We introduce FePd$_{3}$ as a new material for studying thermally active
artificial spin ice (ASI) systems and use it to investigate both the square and
kagome ice geometries. We readily achieve perfect ground state ordering in the
square lattice and demonstrate the highest yet degree of monopole
charge-ordering in the kagome lattice. We find that smaller lattice constants
in the kagome system generally produce larger domains of charge order. Monte
Carlo simulations show excellent agreement with our data when a small amount of
disorder is included in the simulation.
