TY - JOUR ID - 555009 AU - Dubroka, Adam - Cristiani, G. - Habermeier, H.-U. - Humlíček, Josef PY - 2004 TI - Infrared study of YBa2Cu3O7/La0.67Ca0.33MnO3 superlattices JF - Thin Solid Films VL - 2004 IS - 455 SP - 172-176 EP - 172-176 PB - Elsevier science SN - 00406090 KW - Infrared ellipsometry KW - Superlattice KW - La1-xCaxMnO3 KW - YBa2Cu3O7 N2 - The infrared response of superlattices (SLs) composed of YBa2Cu3O7 (YBCO) and La0.67Ca0.33MnO3 (LCMO) on SrTiO3substrate has been studied by ellipsometry in the range from 400 to 5000 cm-1. We use a model calculation of the optical response to distinguish the contribution of the SL and the substrate.The infrared data provide an evidence of a strong interaction between the YBCO and LCMO layers.The mid-infrared resonance located at approximately 1000-3000 cm-1 is discussed in terms of the polaronic absorption in LCMO.The resonance could indicate a charge transfer from the YBCO to the LCMO layers.
