Far-infrared re°ection spectra were analyzed using a tting procedure based on the modi ed plasmon{two phonon interaction model. Together with the strong plasmon{two longitudinal optical phonon coupling we obtained a local mode of Ni at about 180 cm¡1. This mode intensity depends on temperature. Magnetic measurements shows that PbTe alloys doped with Ni reveals weak ferromagnetic interaction between magnetic ions.</dc:description><dc:date>2009</dc:date><dc:date>2012-05-31 13:40:44</dc:date><dc:type>Neznano</dc:type><dc:identifier>26450</dc:identifier><dc:language>sl</dc:language></rdf:Description></rdf:RDF>
