STRUCTURE AND ANTIFERROMAGNETIC PHASE-TRANSFORMATION IN NANOCRYSTALLINE FEF2. JIANG, J., RAMASAMY, S., BIRRINGER, R., GONSER, U., & GLEITER, H. Solid State Communications, 80(7):525--528, November, 1991. WOS:A1991GR86300017

The effect of grain boundaries on the antiferromagnetic order/disorder transition of FeF2 has been investigated by means of Mossbauer spectroscopy. FeF2 specimens containing about 30% grain boundaries were generated in the form of polycrystals (called nanocrystalline FeF2) with an average crystal size of 8 nm. The nanocrystalline FeF2 was produced by means of inert gas condensation. The nanocrystalline FeF2 exhibited a broad range of transition temperature extending from 78 to 66 K as compared to the range of 78 to 75.5 K of coarse-grained FeF2. The magnetic relaxation of the nanocrystalline FeF2 sample was observed at
