Abstract

The primary purpose of this investigation was to determine whether there exists a correlation between the carrier concentration and the saturation magnetic moment of various osmium-iron solid solutions at room temperature. However, as work progressed, it became evident, through deviations of experimental data from hypothesis, that a study of the extraordinary Hall coefficient should also be made. The carrier concentration was determined as a function of per cent osmium in iron and of applied magnetic field intensity, while the extraordinary Hall coefficient was determined as a function of per cent osmium in iron as well as a function of its resistivity. Hall measurements were taken using direct current apparatus with procedure and method based on the works of E. M. Pugh and associates.
