Title: Thickness dependent transport and magnetotransport in CSD grown La{sub 0.7}Pb{sub 0.3}MnO{sub 3} manganite films

Abstract

Highlights: {yields} Thickness dependent transport and MR of CSD grown La{sub 0.7}Pb{sub 0.3}MnO{sub 3} manganite films. {yields} Chemical Solution Deposition (CSD) is the low cost, simple and easy to handle. {yields} Prominent strain effect in lower thickness films. {yields} 3D lattice strain and microstructure govern the transport and MR in the films. {yields} Low temperature resistivity minima is also affected by 3D lattice strain. -- Abstract: We report the effect of film thickness on transport and magnetotransport in La{sub 0.7}Pb{sub 0.3}MnO{sub 3} (LPMO) manganite films grown on single crystalline LaAlO{sub 3} substrate using chemical solution deposition (CSD) technique. AFM measurements show the island type grain growth responsible for the strain at the film-substrate interface, while structural studies using XRD shows the presence of thickness dependent compressive strain in the films which modifies the transport and magnetotransport in LPMO/LAO films. The observation of low temperature resistivity minima behavior in all the LPMO films has been explained in the context of electron-electron scattering mechanism. The ZFC-FC magnetization measurements show the glassy state behavior below T{sub min}.
