Effects of a strong external magnetic field on the reduction of cobalt and iron oxides: Confirmation

Abstract

We have confirmed reports by Rowe et al. indicating that a strong (4.6 kOe) magnetic field influences the rate of reduction of some cobalt and iron oxides. In addition to our earlier gravimetric methods, we simultaneously carried out an evolved gas analysis such as that described by Gallagher et al. The discrepant results may arise from differences in experimental conditions used by the two groups. We used isothermal reduction, whereas Gallagher et al. used constantly increasing temperatures. Perhaps the latter are not sensitive to small changes in rate. (AIP)
