摘要：

It is found that substitutions of Sc by Fe in Li3SC2(PO4)3 and of Fe by Sc in the isostructural compound Li3Fe2(PO4)3 result in suppression of an order-disorder phase transition in the lithium subsystem of the Li3SC2-xFex(PO4)3 mixed crystals. Thus a lithium disorder, dominating at T greater-than-or-equal-to 570 K, is preserved at lower temperatures. This leads to a glassylike behavior of the crystals, in particular, Vogel-Fulcher-Tammann temperature dependence of the ionic conductivity.
