Fe2O3 magnetic nanoparticles

Magnetic γ-Fe2O3 nanoparticles disperse in silica matrix and with a thin layer coating on the surface. It has superparamagnetism and better light transmittance which makeγ-Fe2O3 nanoparticles best materials for spectrum research and detection.
Features:
1. Stable magnetism and can be kept for a long time
2. Complete superparamagnetism
3. 1um-5μm monodisperse magnetic nanoparticles are available
