A LOW-COST AND HIGH-YIELD PRODUCTION OF MAGNETITE NANORODS WITH HIGH SATURATION MAGNETIZATION
Nanopowders of single-crystalline rod-like magnetite have been synthesized in a glycerol-water system under hydrothermal condition by using the goethite (α-FeOOH) precursor. The influence of different reaction parameters on the morphology and composition of the products have been investigat...
