Barium Ferrite Ball Milled In Surfactant

  • Surfactant assisted ball-milling of barium ferrite -

    Abstract: The effects of wet-milling barium ferrite in the presence of cationic or anionic surface active substances have been investigated by X-ray diffraction and Moss spectroscopy measurements. Evidence for superparamagnetic relaxation of fine particles, both in the surfactant assisted ball-milled samples and in samples dry-milled in air is obtained from the room temperature and 4.2 K
