N2 - Atomic resolution scanning transmission electron microscopy and electron energy loss spectroscopy combined with ab initio electronic calculations are used to determine the structure and properties of the Fe 3 O 4 (111)/SrTiO 3 (111) polar interface. The interfacial structure and chemical composition are shown to be atomically sharp and of an octahedral Fe/SrO 3 nature. Band alignment across the interface pins the Fermi level in the vicinity of the conduction band of SrTiO 3 . Density functional theory calculations demonstrate very high spin-polarization of Fe 3 O 4 in the interface vicinity which suggests that this system may be an excellent candidate for spintronic applications.
