Charge ordering transition near the interface of the (011)-oriented La1−xSrxMnO3 (x∼1/8) films
Two clear phase transitions, an insulator to metal transition followed by a metal to insulator transition on cooling, were realized in La1−xSrxMnO3 (x∼1/8) (LSMO) thin films grown on (011) SrTiO3 substrates due to the substrate-imposed anisotropic stain. Effects of phase transitions on the rectifying behavior of the corresponding junction LSMO/Nb:SrTiO3 were further investigated.
The paramagnetic/insulator to ferromagnetic/metal transition led to a decrease in built-in potential of the junction, while the metallic to charge/orbital ordering transition results in a growth of interfacial barrier, which could be explained by Fermi-level shifts and the gap opening/closing in LSMO films.
These results indicate the occurrence of clear phase transitions in the vicinity of interface in (011)-LSMO films.
