    • Yielding and flow of highly concentrated, few-layer graphene suspensions 

      COLEMAN, JONATHAN; MOEBIUS, MATTHIAS (2015)
      For a wide range of applications of graphene suspensions, a thorough understanding of their rheological properties is crucial. We probe the microstructure of dense suspensions of micron-sized, few-layer, defect-free graphene ...
    • Yoke-shaped MgO-barrier magnetic tunnel junction sensors 

      COEY, JOHN (2012)
      Yoke-shaped sensors based on MgO-barrier magnetic tunnel junctions have been designed, fabricated, and studied; they show a good linear tunneling magnetoresistance (TMR) response. A nearly-perpendicular configuration of ...
    • Z-Cone model for the energy of an ordered foam 

      HUTZLER, STEFAN; WEAIRE, DENIS (2014)
      We develop the Z-Cone Model, in terms of which the energy of a foam may be estimated. It is directly applicable to an ordered structure in which every bubble has Z identical neighbours. The energy (i.e. surface area) may ...
    • Z-pinch Discharge in Laser Produced Plasma 

      LUNNEY, JAMES; STERLING, ENRIQUE (2010)
      Z-pinch effects in a laser produced aluminium plasma were investigated with a relatively low current fast coaxial electrical discharge. The ion flux in the laser produced plasma (LPP) was monitored with a Langmuir ion ...
    • The zero-magnetization Heusler ferrimagnet 

      COEY, JOHN; VENKATESAN, MUNUSWAMY; RODE, KARSTEN; ACKLAND, KARL (2013)
      An unusual zero-moment half-metallic state has been predicted in stoichiometric Heusler compounds with 24 valence electrons, where, unlike an antiferromagnet, the two sublattices are chemically or crystallographically ...
    • The zero-moment half metal: How could it change spin electronics? 

      Coey, John; Rode, Karsten; Stamenov, Plamen; Atcheson, Gwenael (2016)
      The Heusler compound Mn2RuxGa (MRG) may well be the first compensated half metal. Here, the structural, magnetic and transport properties of thin films of MRG are discussed. There is evidence of half-metallicity up to x = ...
    • Untitled 

      SHVETS, IGOR (2013)
      The spatial resolution of a scanning tunneling microscope (STM) can be enhanced using light element-terminated probes with spatially localized electron orbitals at the apex atom. Conductive diamond probes can provide carbon ...
