Pyrochlore iridate films, a family of cubic 5d transition metal oxides, can be mother compound, where various correlated topological phases can be studied by manipulating magnetism with lattice strain. However, in situ epitaxial growth has been known to be notoriously difficult. In this talk, I am going to talk about the recent progress in the study of pyrochlore iridate thin films focusing on the emergent topological properties of in-situ grown fully strained Nd2Ir2O7 thin films. A fully strained film with antiferromagnetism shows an anomalous Hall conductivity which is an order of magnitude larger than that in the bulk or the relaxed film. Moreover, the large spontaneous Hall conductivity is observed due to the strain-induced magnetic T1-octupole, which clearly demonstrates that topological properties can be engineered by manipulating magnetism with strain.
