Pressure Dependence of Electrical Resistivity for Magnesium-Based Amorphous Alloys

摘要

Measured pressure coefficients of resistance and the corresponding pressure coefficients of resistivity, estimated using law of mixtures isothermal compressibility values, are reported for a series of magnesium-based amorphous alloys. The pressure coefficients correlate with the thermopower and the resistivity. When combined with results for non-magnetic amorphous alloys containing transition metals, there are suggestions of universal correlations between the pressure coefficients and the electrical resistivity. Data are discussed in the framework of the diffraction model.
