Rogalev Europium nitride is semiconducting and contains nonmagnetic Eu 3+ , but substoichiometric EuN has Eu in a mix of 2+ and 3+ charge states. We show that at Eu 2+ concentrations near 15%–20% EuN is ferromagnetic with a Curie temperature as high as 120 K. The Eu 3+ polarization follows that of the Eu 2+ , con... [Phys. Rev.
