In recent years titanium nitride is being considered as a very promising
plasmonic material for data storage applications as it exhibits a pronounced
plasmonic dipolar resonance and has high thermal stability. However, there is a
lack of research where higher order resonance modes are examined. We address
this here by performing angle dependent spectral transmission measurements
nanodisks arrays made from titanium nitride. The measurements show strong
polarization dependence with s-polarized light causing excitation of the
quadrupole and higher order resonance plasmonic modes. These higher order modes
are required for the state-of-the-art designs of near-field transducers. This,
together with its outstanding thermal properties, makes TiN a favourable
material for data storage applications.
