Novel Rare-Earth Magnetic Nitride Perovskites*

In this talk, we present perovskite nitrides with magnetic rare-earth metals as novel materials for magnetic applications. These materials appear to be thermodynamically stable and, in spite of possessing different crystal structures and different atomic environments, they retain the magnetic moment of the corresponding elemental rare-earth metal. We find both magnetic metals and semiconductors, with a wide range of magnetic moments and record high magnetic anisotropy energies. Further tuning of the electronic and magnetic properties can also be expected by doping with other rare-earths or by creating solid solutions.
