Abstract From the perspectives of scientific researches and practical applications, it is desirable to explore high operating temperature ferromagnetic films. The effect of biaxial strain on magnetic properties of (110)-oriented La 0.7 Sr 0.3 MnO 3 films was studied. High quality La 0.7 Sr 0.3 MnO 3 films were grown on (110)-oriented perovskite single crystal substrates using pulsed laser deposition, varying substrate-induced misfit strains from − 2.27–0.75%. A remarkable enhancement of Curie temperature has been achieved for (110)-oriented La 0.7 Sr 0.3 MnO 3 films clamped with small misfit strains (i.e., grown on LAST (110)). The enhanced Curie temperature of (110)-oriented La 0.7 Sr 0.3 MnO 3 films could be attributed to the misfit strain between the films and the underlying substrates and may have technological implication for applications at high temperature environments.
