Possibilities for using a pulsed magnetic field to influence structural states in oxide glass

Abstract

The structural-energy spectrum of the states of a bismuth-containing oxide glass, the sensitivity of these states to the action of a pulsed magnetic field, and the thermodynamic and kinetic stability of the structure excited by a pulsed magnetic field are studied by the method of measuring the internal friction. It is established that a pulsed magnetic field influences the structural states and that this leads to irreversible changes in the structure and the crystallization parameters of the glass. It is found that the efficacy of acting on a material with a pulsed magnetic field also depends on the parameters of the field and the structural-energy state of the material and that the action itself is of a thermally-activated relaxational character. The optimal conditions for the action of a pulsed magnetic field on glass are determined.
