The double perovskite La2NiMnO6 (LNMO) exhibits complex magnetism due to thecompetition of magnetic interactions that are strongly affected by structuraland magnetic inhomogeneities. In this work, we study the effect of oxygenannealing on the structure and magnetism of epitaxial thin films grown bypulsed laser deposition. The key observations are that a longer annealing timeleads to a reduction of saturation magnetization and an enhancement in theferromagnetic transition temperature. We explain these results based uponepitaxial strain and oxygen defect engineering. The oxygen enrichment byannealing caused a decrease in the volume of the perovskite lattice. Thisincreased the epitaxial strain of the films that are in-plane locked to theSrTiO3 substrate. The enhanced strain caused a reduction in the saturationmagnetization due to randomly distributed anti-site defects. The reduced oxygendefects concentration in the films due to the annealing in oxygen improved theferromagnetic long-range interaction and caused an increase in the magnetictransition temperature.
