A review on the state-of-arts of perovskite Fe4N thin films and heterostructures with promising appolication potentials in advanced spintronics is presented. the brief introduction is followed by a highlight of the crystal structures and physical properties of pervskite Fe4N, and then a comprehensive description on a series of topics on Fe4N, including the preparations of polycrys-talline Fe4N thin films, epitaxial Fe4N, Fe4N/CoN bilayers, and Fe4N /Alq3/Co spin-valves on one hand, and on the other hand the characterizations on morphology and microstructures, magnetic properties, exchange bias, spin-dependent electrical transport and magnetoresistance etc, of the tunneling junctions with the Fe4N electrodes. Finally, a short summary with updated perspectives on recent researches on Fe4N is given.
