We report the magnetic properties for dispersed, spherical Fe3O4 and gamma-Fe2O3 particles similar to 250 nm in diameter in the temperature range T = 4.2-294 K. For Fe3O4, hysteresis properties show anomalies at 130 K, where the magnetocrystalline anisotropy constant K-1 vanishes; the ra...
Mixtures of γ-Fe2O3 NPs with very few amount of Pt and Pd (1 wt%) are converted into cryogels with high surface areas and high porosity and deposited as thin films on modified ITO substrates. Then, the catalytic activity of these multicomponent (noble metal-metal oxide) cryogels towards...
