  • Chemical pressure and magnetic field effects in CePtGa 
    Ragel, F. C.; P de V du Plessis; A M Strydom (IOP PUBLISHING LTD, 2007)
    The antiferromagnetic Kondo compound CePtGa and the Ce(Pt1−xNix)Ga and CePt(Ga1−yAly) alloy systems have been studied by resistivity ρ(T), magnetoresistivity MR and susceptibility χ(T) measurements on polycrystalline samples ...
  • Competing effects by Y dilution in CeNiAl4 
    Ragel, F. C.; P de V du Plessis; A M Strydom (Solid State Communications, 2007)
    The occurrence of a maximum at a temperature T-max in the resistivity of the dense Kondo compound CeNiAl4 and in (Ce1-x,Y-x)NiAl4 alloys is investigated. Tmax (proportional to T-K, the Kondo temperature) first increases, ...
  • Dilution and Non-Fermi-liquid effects in the CePtIn Kondo lattice 
    Ragel, F. C.; P de V du Plessis; A M Strydom (Journal of Physics, 2009)
    Measurements of electrical resistivity (ρ(T)), magnetoresistivity (MR), magnetic susceptibility (χ(T)) and heat capacity (CP(T)) are presented for the (Ce1−xLax)PtIn alloy system of which the CePtIn parent is a known dense ...
  • Effects of La dilution on the CePt2Si2 Kondo lattice 
    Ragel, F. C.; P de V du Plessis; A M Strydom (IOP PUBLISHING LTD, 2008)
    Electrical resistivity (ρ(T)) and magnetoresistivity (MR) measurements are presented for the (Ce1−xLax)Pt2Si2 alloy system. ρ(T) data at low temperatures for alloys in the concentrated Kondo lattice regime 0≤x≤0.2 conform ...
  • Electrical transport of Ce(Pt1-xNix)Ga and CePt(Ga1-yAly) alloys 
    Ragel, F. C.; P de V du Plessis; A M Strydom (ELSEVIER SCIENCE BV, 2007)
    Electrical resistivity results of Ce(Pt1-xNi)Ga and CePt(Ga1-yAl) alloys show features at low temperature indicating antiferromagnetic ordering and Kondo behaviour. The variation of Néel temperature with alloy composition ...
  • Kondo behaviour of the solid solution (Ce1-xLax)PtGa 
    Ragel, F. C.; P de V du Plessis; A M Strydom (Journal of Physics and Chemistry of Solids, 2010)
    The solid solution (Ce1−xLax)PtGa has been studied through X-ray diffraction, magnetization (σ(B)), magnetic susceptibility (χ(T)), electrical resistivity (ρ(T)), magnetoresistivity (MR) and heat capacity (CP(T)) measurements. ...
