Abstract
Amorphous Fe2SiO4 synthesized at elevated pressures exhibits a Néel transition at a temperature identical to that observed in the crystalline form, TN = 65 (±2) kelvin at zero pressure. This behavior contrasts sharply with observations on other disordered systems, such as spin glasses, which characteristically exhibit strong "frustration" of the spins and consequent marked suppression of the Néel transition.Keywords
