Abstract

A first study of the effect of weak pulsed magnetic fields (PMFs) on Sb1−x Asx solid solution crystals is reported. An effect of long-time (months) redistribution of the solid solution components at room temperature after a short (seconds) exposure to a PMF was revealed. The effect includes stages of enrichment of the crystal surface in antimony with the formation of clusters, antimony cluster breakup, and a decrease in surface antimony content, which is accompanied by a substantial improvement in solid-solution homogeneity. The PMF-induced component redistribution entails a decrease in the crystal melting temperature. Rupture of stressed chemical bonds in arsenic vacancy complexes, which is induced by a change in their multiplicity under PMF exposure, is considered as a possible trigger mechanism.
