Magnetic anisotropy plays an important role in the development of manganite-based magnetic devices. Establishing a deeper understanding of the anisotropy in manganites is useful for controlling their magnetic properties. We have studied the structure, lattice strain, and magnetic properties of La0.5Ba0.5MnO3 (LBMO-5) films with the thickness of 12 nm-96 nm, grown on the (001) SrTiO3 (STO) substrate. The LBMO-5 films are grown with high crystalline quality. The orientation relationship between the LBMO-5 film and the STO substrate [(001)f//(001)...
