Spectral weight redistribution in (LaNiO3)n/(LaMnO3)2 superlattices from optical spectroscopy

P. Di Pietro, J. Hoffman, A. Bhattacharya +2

We have studied the optical properties of four (LaNiO${}_3$)${}_n$/(LaMnO${}_3$)${}_2$ superlattices (SL) ($n$=2, 3, 4, 5) on SrTiO${}_3$ substrates. We have measured the reflectivity at tem…
