(Color online) HL reciprocal space map around (103) asymmetric Bragg reflection for three selected LSMO samples is reported. From left to the right, the maps correspond to LSMO thin film annealed for 30, 60, and 120 min, respectively. These correspond to sample LSMO-B, LSMO-C, and LSMO-E, defined later in Table I, respectively.
(Color online) Rocking curves around (002) symmetric Bragg reflection for three selected LSMO samples (same samples reported in Fig. 1). For clarity, data are shifted of 0.2 both in x and y directions. In the inset, rocking curve of STO substrate around (002) symmetric Bragg is reported too.
(Color online) Resistivity curves as a function of temperature of a set of LSMO samples, for different annealing processes (sample code is defined in Table I). For sake of clarity, the graph has been break up in two sections, the lower part in linear scale, and the upper part in log-scale. In the inset, the metal-insulator transition temperature TMI as a function of the out-of-plane LSMO films lattice parameters (the region with TMI > 430 K corresponds to a transport regime where any possible polaronic insulating state is destroyed by the thermal energy, see Ref. 25). Lines are just guides for eyes.
Metal-insulator transition temperature TMI and out-of plane lattice parameter for a set of LSMO samples. LSMO-A and LSMO-F correspond to the as-grown LSMO film and the LSMO film annealed for the longest time (i.e., 240 min), respectively.
