  • Fluctuations and the ferromagnetic instability in YFe2Al10: the role of Fe stoichiometry 
    Strydom, A. M.; Khuntia, P.; Baenitz, M.; Peratheepan, P.; Steglich, F. (Physica Status, 2013)
    YFe2Al10 forms in a well-ordered crystal structure, with a unique site for the magnetic atom Fe. At elevated temperatures YFe2Al10 behaves electronically as a good metal. At low temperatures on the other hand, signatures ...
  • Hypergeometric Equation in Modeling Relativistic Isotropic Sphere 
    Thirukkanesh, S.; Ragel, F. C. (International Journal of Theoretical Physics, 2014)
    We study the Einstein system of equations in static spherically symmetric spacetimes. We obtained classes of exact solutions to the Einstein system by transforming the condition for pressure isotropy to a hypergeometric ...
  • 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. ...
  • Mechanical Properties of Poly(vinyl alcohol) Montmorillonite Nanocomposites. 
    Soundararajah, Q. Y.; Karunaratne, B. S. B.; Rajapakse, R. M. G. (J. Compos. Mater., 2010)
    The properties of polymers are greatly enhanced when they are incorporated with silicate-layered clays as they find many applications in the fields of electronics, automobile industry, packaging, and construction. In this ...
  • Microstructure of InxGa1-xN nanorods grown by molecular beam epitaxy 
    Soundararajah, Q. Y.; Webster, R. F. (Semicond. Sci. Technol, 2015)
    Transmission electron microscopy is used to examine the structure and composition of InxGa1−xN nanorods grown by plasma-assisted molecular beam epitaxy. The results confirm a core–shell structure with an In-rich core and ...
  • Montmorillonite polyaniline nanocomposites: Preparation, characterization and investigation of mechanical properties 
    Soundararajah, Q. Y.; Karunaratne, B. S. B.; Rajapakse, R. M. G. (Mater. Chem. Phys, 2009)
    The interest in clay polymer nanocomposites (CPN) materials, initially developed by researchers at Toyota, has grown dramatically over the last decade. They have attracted great interest, both in industry and in academia, ...
  • Preparation, Characterisation and Mechanical Properties of Montmorillonite Polyanyline Nanocomposites 
    Soundararajah, Q. Y.; Karunaratne, B. S. B.; Rajapakse, R. M. G. (University of Peradeniya, 2006)
    The montmorillonite (MMT) clay was intercalated with polyaniline (PANI) to prepare montmorillonite - polyaniline nanocomposites (MMT-PANI). The MMT clay was ion exchanged with H+ and dried at 120°C for 2 hours. The H+ ...
  • A realistic model for charged strange quark star 
    Thirukkanesh, S.; Ragel, F. C. (CHINESE PHYSICAL SOC, PEOPLES R CHINA and IOP Publishing Ltd, 2017)
    e report a general approach to solve an Einstein-Maxwell system to describe a static spherically symmetric anisotropic strange matter distribution with linear equation of state in terms of two generating functions. It is ...
  • Strange star model with Tolmann IV type potential 
    Thirukkanesh, S.; Ragel, F. C. (Astrophysics and Space Science, 2014)
    We report a general solution in one of the gravitational potentials to the Einstein system in static spherically symmetric spacetime, modeling anisotropic strange quark matter by imposing a linear barotropic equation of ...
  • Transition from dense Kondo to the intermediate-valence regime in the Ce (Pt1-xNix)2Si2 alloys 
    Ragel, F. C.; P de V du Plessis (Journal of Physics: Condensed Matter, 2004)
    Electrical resistivity ρ(T) measurements on polycrystalline samples of the Ce (Pt1−xNix)2Si2 system exhibit dense Kondo behaviour for alloys with . The temperature at which a maximum appears in ρ(T) shifts from Tmax = 65 ...
