  A giant thermal magnetoresistance is predicted for the electromagnetic
transport of heat in magneto-optical plasmonic structures. In chains of InSb-Ag
nanoparticles at room temperature, we found that the resistance can be
increased by almost a factor of 2 with magnetic fields of 2 T. We show that
this important change results from the strong spectral dependence of localized
surface waves on the magnitude of the magnetic field.
