文摘

The magnetic nanocomposites were prepared by calcining Fe(NO3)3 and carbon precursor mixture in Ar and at low temperature. The magnetic property was tuned by varying calcination temperature, gas flow rate, retention time, and heating rate. The saturation magnetization relies on the spatial and temporal contact of Fe intermediates with NO2 and O2 byproducts.
