Abstract

We have synthesized epitaxial thin films of La1−xSr1+xMnO4 with x = 0.0 and x = 0.5 by pulsed laser deposition on NdGaO3 and LaSrAlO4 substrates with different lattice mismatch. X-ray analysis shows that these layered doped manganites can be grown fully strained allowing to tune the lattice degrees of freedom which otherwise are a function of chemical composition x. Since the crystal structure is strongly coupled to the magnetic, orbital, and charge degrees of freedom in the doped manganites, the demonstrated strain engineering is the base for an extrinsic control of, e.g., charge-orbital order.
