Abstract

Lattice distortions, be they in the form of chemical and hydrostatic pressure in bulk or lattice mismatch between film and substrate, have significant effects on the transport as well as the magnetic properties of colossal magnetoresistance (CMR) materials. We summarize here our results on tensilely and compressively strained La0.7Sr0.3MnO3 (LSMO) thin films that indicate the important role of lattice distortions due to the lattice mismatch between the film and substrate. The strain due to lattice distortions can be used to tune the magnetic domain structure, magnetization, magnetic anisotropy and magnetotransport of LSMO thin films.

18. In magnetic crystals, the spin-orbit interaction, which is at the microscopic origin of this resistivity anisotropy or anisotropic MR (AMR) effect, leads to a resistivity which depends not only on the orientation of magnetization and current and but also on the relation of these vectors to the crystal structure. For example, resistivity anisotropy of this type has recently been reported for transition metal epitaxial thin films.Google Scholar
