Abstract

Abstract BaOFe 2O 3 binary glasses have been prepared by the splat quenching method. The structural change of the glassy state during the crystallization has been studied by means of Mössbauer spectroscopy and high voltage electron microscopy. The magnetic properties of these crystallized glasses have been measured by the vibrating-sample magnetometer and have been discussed in terms of the particle size of precipitated BaO·6Fe 2O 3. The crystallized glass, having 800Å of BaO·6Fe 2O 3 particles, showed the maximum coercive force, that is, 6.2kOe which is three times than that of commercial BaO·6Fe 2O 3.
