“…For frequency regions above 20 eV, we extended reflectance at 20 eV -30 eV as a constant and then assumed ω -4 dependence. 28,29 We further confirmed that the results from ITMM and KK analyses using R(ω) were consistent. …”

“…The observed temperature dependence is consistent with the theoretical approach by Millis et al, 4 who went beyond Zener's double exchange 5 and included dynamic JT polaron effects. Subsequent studies in crystalline 6,7,8,9 and thin film 10,11 samples confirmed the existence of the mid-infrared (MIR) excitation for a large number of manganites. In this context the concept of small (SP) and large polarons (LP) as essential ingredients to understand the electronic transport properties and the MIR excitation (labeled polaronic peak in the following) became subject of considerable theoretical efforts.…”

“…Optical microscopy studies confirmed that the bc-plane of our sample was very clean. Near normal incident reflectivity spectra R(ω) of the b-and c-axes were measured between 5 meV and 20 eV using polarized light [9]. The corresponding σ(ω) were obtained using Kramers-Kronig analysis.…”
