Static properties (0–5.5 T, 2–300 K) of g-Fe2O3 5- and 9-nm particles trapped in a silica xerogel (Fe/Si- 0.01 0.44 mol/mol) give evidence of strains. Comparing with dispersions in a polyvinylic alcohol suggests that the temperature dependence of the coercivity could reflect an intrinsic interparticle interaction effect.

Abstract
Static properties (0–5.5 T, 2–300 K) of g-Fe2O3 5- and 9-nm particles trapped in a silica xerogel (Fe/Si- 0.01 0.44 mol/mol) give evidence of strains. Comparing with dispersions in a polyvinylic alcohol suggests that the temperature dependence of the coercivity could reflect an intrinsic interparticle interaction effect.File in questo prodotto:
