Silicon 209-216 patatin like phospholipase domain containing 6 Homo sapiens 153-156 26196377-1 2015 Cubic La(Fe,Si)13-based compounds have been recently developed as promising negative thermal expansion(NTE) materials, but the narrow NTE operation-temperature window(~110 K) restricts their actual applications.

Silicon 12-14 patatin like phospholipase domain containing 6 Homo sapiens 134-137 26196377-2 2015 In this work, we demonstrate that the NTE operation-temperature window of LaFe(13-x)Si(x) can be significantly broadened by adjusting Fe-Fe magnetic exchange coupling as x ranges from 2.8 to 3.1. Silicon 84-86 patatin like phospholipase domain containing 6 Homo sapiens 38-41 26196377-5 2015 The reduction of the overall Fe-Fe magnetic exchange interactions contributes to the broadness of NTE operation-temperature window for LaFe(13-x)Si(x).
