      abstract     = {Antiperovskite manganese nitrides have intriguing magnetic
                      and electronic properties that are not well understood. Just
                      as their perovskite oxide counterparts, they are expected to
                      display properties tunable through epitaxial strain
                      engineering, which has barely been explored yet. Here, three
                      notable contributions are made to the understanding and
                      tuning of these fascinating materials, focusing on
                      Mn$_3$NiN. First, combining X-ray spectroscopy measurements
                      and first-principles calculations, an unusually large
                      negative oxidation state of Ni$^{3−}$is reported. Second,
                      a substantial shift of the antiferromagnetic ordering
                      temperature by 116 K, from 266 to 150 K, is reported by
                      growing Mn3NiN films on different substrates. This shift is
                      due to the mixed contributions of ferrimagnetic and
                      antiferromagnetic phases. Third, a plasmonic signature with
                      a high optical extinction coefficient in the infrared to
                      visible range is exhibited, tunable by different substrates.
                      The findings suggest that Mn3NiN has significant potential
                      in antiferromagnetic spintronics, and plasmonics, expanding
                      the scope of new materials for electromagnetic
                      field-controlled plasmonics, piezo spintronics, and
                      multicaloric applications.},
