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…
Systematic Raman study of optical phonons in BaCuO ( = Y, Dy, Gd, Sm, Nd): Antiferromagnetic coupling strength versus lattice parameters
Silvia Müllner, Wayne Crump, Dirk Wulferding +4
We present a systematic study of the interplay between lattice parameters and the energy of the optical phonons as well as the antiferromagnetic coupling strength, , in the high…
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…
Nano-engineering of electron correlation in oxide superlattices
J. Laverock, M. Gu, V. Jovic +5
Oxide heterostructures and superlattices have attracted a great deal of attention in recent years owing to the rich exotic properties encountered at their interfaces. We focus on t…
Observation of weakened V-V dimers in the monoclinic metallic phase of strained VO2
J. Laverock, V. Jovic, A. A. Zakharov +6
Emergent order at mesoscopic length scales in condensed matter can provide fundamental insight into the underlying competing interactions and their relationship with the order para…
Enhanced electron correlations at the SrxCa1-xVO3 surface
J. Laverock, J. Kuyyalil, B. Chen +5
We report hard x-ray photoemission spectroscopy measurements of the electronic structure of the prototypical correlated oxide SrxCa1-xVO3. By comparing spectra recorded at differen…
