Low-energy (0.5-4 meV) charge dynamics of the typical charge-ordered manganite Pr0.7Ca0.3MnO3 have been investigated directly by using THz time-domain spectroscopy. We observed a finite peak structure in the complex optical spectrum around 2-3 meV well below the charge gap ∼300 meV and attributed it to the collective excitation mode arising from the charge-density-wave condensate. © 2003 Elsevier Science B.V.
