  • Influence of growth morphology on the Neel temperature of CrRu thin films and heterostructures 
    Prinsloo, A.R.E.; Derrett, H.A.; Hellwig, O.; Fullerton, E.E.; Alberts, H.L.; Van den Berg, N.G. (Elsevier, 2009)
    Dimensionality effects on epitaxial and polycrystalline Cr1-xRux alloy thin films and in Cr/Cr–Ru heterostructures are reported. X-ray analysis on Cr0.9965Ru0.0035 epitaxial films indicates an increase in the coherence ...
  • An investigation of green iridescence on the mollusc Patella granatina 
    Brink, D.J.; Van den Berg, N.G. (American Institute of Physics, 2005-01)
    In this paper we investigate the relatively rare phenomenon of iridescence on the outer surface of seashells (not the well known pearly inner surfaces). Using reflection spectroscopy and scanning electron microscopy we ...
  • Unusual coloration in scarabaeid beetles 
    Brink, D.J.; Van den Berg, N.G.; Prinsloo, Linda Charlotta; Hodgkinson, I.J. (American Institute of Physics, 2007-04-07)
    In this paper we investigate the reflection of circularly polarized light from the exocuticle of the scarabaeid beetle Gymnopleurus virens. Reflection spectra are deeply modulated, exhibiting a number of relatively narrow ...
