Skandija fluorīda elektronu paramagnētiskās rezonanses spektri

subject

description

Darba ietvaros veikti punktveida defektu pētījumi monokristāliskos un polikristāliskos ScF3 paraugos ar elektronu paramagnētiskās rezonanses (EPR) metodi istabas un šķidrā slāpekļa temperatūrās. Monokristāla parauga EPR spektru leņķiskās atkarības liecina par Gd3+ piejaukuma jonu Sc3+ pozīcijā. Literatūrā līdz šim nav viennozīmīgi noteiktas gadolīnija jona EPR spektru parametru vērtības, tādēļ tās šeit tiek precizētas, kā arī aprēķinātas teorētiski ar superpozīcijas modeli (SM), lai noskaidrotu ScF3 kristāla negatīvās termiskās izplešanās (NTE) ietekmi uz parametru vērtībām. Pulvera paraugu spektru modelēšanai nepieciešams ņemt vērā defekta mijiedarbību ar sešiem tuvākajiem fluoru joniem. Darbā tiek piedāvāti iespējamie defekta modeļi.
