Current research interest on low power consumption and high speed spintronic devices demands the development of interfacial multiferroics comprising of an oxide ferromagnet (FM) and a ferroelectric (FE) material. Among oxide FMs, perovskite manganites, in particular, La_1-xSr_xMnO₃ (LSMO) with x=0.3-0.4 have potential for different applications due to the unique properties such as half metallicity, i.e., high spin polarization, and high Curie temperature. In this work, we report on the effect of strain due to lattice mismatch on the static and dynamic magnetic properties of LSMO thin films. We use two different substrates having different lattice parameters to induce distinct lattice mismatch strains in LSMO thin films.
