Abstract
The pressure dependence of the phonon spectrum of three La1 - xCaxMnO3 - δ manganites have been studied by means of Far-IR absorption spectroscopy coupled with a Diamond Anvil Cell. The effect of the applied pressure on the charge delocalization have been investigated defining the nature of the metallization process in the low-frequency domain.File allegati a questo prodotto
