AbstractThe Hall and Seebeck effects of the stripe-ordered superconductor La1.6-xNd0.4SrxCuO4 single crystals (x = 0.10, 0.12 and 0.15) were investigated systematically. The sign change of Hall and Seebeck coefficients (R-H and S) from positive to negative with decreasing temperature suggests the presence of electron pockets in the Fermi surface due to the stripe ordering. We successfully tune this behavior through an epitaxial strain induced by the mismatch between the thin film and the substrate. The negative R-H disappears in the thinner film in which the static charge stripe is greatly suppressed by the strong epitaxial strain, and for a strain released thicker film the negative R-H recovers. These results indicate the possibility of Fermi surface reconstruction caused by the static charge stripe order in the system.
