Van Hove singularities at the -face of the lutetium nitride phonon dispersion
M. Markwitz, K. Kneisel, R. G. Buckley +9
We report the structural and vibrational properties of the prototypical 4-filled nonmagnetic member LuN of the lanthanide nitrides, \textit{Ln}N, with elastic and inelastic neut…
Tuneable magnetic behaviour, electronic structure and nitrogen vacancy formation in GdSmN
Omri Porat, Elma Joshy, Jackson Miller +2
The rare earth nitrides are the only series of intrinsic ferromagnetic semiconductors where the interplay of spin and unquenched orbital angular momentum provides access to a range…
Optical, vibrational, and electronic properties of semiconducting YbN
M. Markwitz, C. Pot, R. G. Buckley +2
We investigate the vibrational, optical, and electronic properties of insulating YbN thin films using Raman spectroscopy, Fourier-transform infrared spectroscopy, and electrical tr…
Rare-Earth Nitrides: Fundamental Advances and Applications in Cryogenic Electronics
W. F. Holmes-Hewett, J. D. Miller, H. G. Ahmad +2
Driven by the pursuit of high-performance electronic devices, research into novel materials with properties appropriate for cryogenic applications has unveiled the exceptional prop…
Conductivity of high-mobility epitaxial GdN
Edward X. M. Trewick, B. J. Ruck, W. F. Holmes-Hewett +1
We report electron transport studies of a (001) GdN film grown on the square net presented by the (001) surface of LaAlO3, motivated by recent advances in epitaxial thin-film growt…
Spin polarisation and non-isotropic effective mass in the conduction band of GdN
W. F. Holmes-Hewett, E. X. M. Trewick, H. J. Trodahl +2
GdN is a ferromagnetic semiconductor which has seen increasing interest in the preceding decades particularly in the areas of spin- and superconducting- based electronics. Here we…
Unconventional superconductivity and quantum criticality in SmN
W. F. Holmes-Hewett, K. Van Koughnet, J. D. Miller +3
Nitrogen vacancy doped SmN is a semiconductor which lies in the intermediary between insulating-ferromagnetic SmN and metallic-anti-ferromagnetic Sm. The dopant electrons r…
4f Conduction in the Magnetic Semiconductor NdN
W. F. Holmes-Hewett, R. G. Buckley, B. J. Ruck +2
We report the growth of films of the intrinsic ferromagnetic semiconductor NdN, and an investigation of their optical and transport properties. There is clear evidence of a strong…
Optical Spectroscopy of SmN: Evidence for 4f Transport
W. F. Holmes-Hewett, R. G. Buckley, B. J. Ruck +2
The rare-earth nitride ferromagnetic semiconductors owe their varying magnetic properties to the progressive filling of 4f shell across the series. Recent electrical transport meas…
