Abstract
Alpha-FeOOH nanorods with diameters of 15-25 nm and lengths up to 170-300 nm were synthesized in high yield via a facile and template-free hydrothermal method at low temperature. After calcining the as-synthesized alpha-FeOOH at 250 degrees C for 2 h, we could obtain alpha-Fe2O3 nanorods. Interestingly, the as-obtained alpha-Fe2O3 nanorods exhibited weakly ferromagnetic characteristics at low temperature and superparamagnetic property at room temperature, which is different from the behavior of the corresponding bulk material.This publication has 34 references indexed in Scilit:
