  • Nkosi, SS; Lafane, S; Masina, Bathusile N; Ndwandwe, OM (Elsevier, 2016-12)
    The magnetic properties of paramagnetic/weakly ferromagnetic films are strongly affected by the proximity to materials that undergo a metal to insulator phase transition. Here, we show that under the deposition conditions ...
  • Nkosi, SS; Kortidis, I; Motaung, DE; Makgwane, PR; Ndwandwe, OM; Ray, SS; Kiriakidis, G (Elsevier, 2014-11)
    Pure and manganese (Mn) ion-doped TiO(sub2) films were grown by pulsed laser deposition under vacuum at different substrate temperatures 350 and 580 C for 50 min each. The concentration of the Mn inTiO(sub2) films was ...
  • Masina, BN; Forbes, A; Ndwandwe, OM; Hearne, G; Mwakikunga, BW (2009-03)
    In this study the authors make use of laser heating of HTHP industrial diamond, as well as the optically measured temperature profile of the diamond surface, to study temperature induced changes to the diamond structure, ...
