Raman signature of cation vacancies in rare-earth nitrides
M. Markwitz, K. Van Koughnet, K. Kneisel +6
We report a coordinated Raman/computation study of the rare-earth nitrides, a series of intrinsic ferromagnetic semiconductors, to reveal the presence of cation vacancies. Their pr…
Perpendicular magnetic anisotropy in CoMnGa
B. M. Ludbrook, B. J. Ruck, S. Granville
We report perpendicular magnetic anisotropy in the ferromagnetic Heusler alloy CoMnGa in a MgO/CoMnGa/Pd trilayer stack for CoMnGa thicknesses up to 3.5 nm. There is a…
Europium nitride: A novel diluted magnetic semiconductor
Do Le Binh, B. J. Ruck, F. Natali +7
Europium nitride is semiconducting and contains non-magnetic \3+, but sub-stoichiometric EuN has Eu in a mix of 2+ and 3+ charge states. We show that at \2+ ~concentrations near 15…
Spin/orbit moment imbalance in the near-zero moment ferromagnetic semiconductor SmN
Eva-Maria Anton, B. J. Ruck, C. Meyer +6
SmN is ferromagnetic below 27 K, and its net magnetic moment of 0.03 Bohr magnetons per formula unit is one of the smallest magnetisations found in any ferromagnetic material. The…
Epitaxial integration of the intrinsic ferromagnetic semiconductor GdN with silicon technology
F. Natali, N. O. V. Plank, B. J. Ruck +4
A major challenge for the next generation of spintronics devices is the implementation of ferromagnetic-semiconductor thin films as spin injectors and detectors. Spin-polarised car…
