Negative thermal expansion (NTE) is an unusual yet highly useful phenomenon that has been extensively studied in numerous crystals, including ceramics, alloys, and metal-organic frameworks. This Letter reports an unprecedented NTE in an amorphous ${\text{Fe}}_{87.5}{\mathrm{Y}}_{3}{\text{Zr}}_{1.5}{… [Phys. Rev. Lett. 135, 106101] Published Wed Sep 03, 2025
