Abstract
In this paper we study the magnetic susceptibilities in quantum wires of IV-VI semiconductors under a parallel magnetic field on the basis of a newly derived one-dimensional electron dispersion law. It is found, taking quantum wires of PbS, PbSe and PbTe as examples, that both the susceptibilities increase with decreasing electron concentration and decreasing film thickness respectively. The paramagnetic-to-diamagnetic susceptibility ratio for electrons in IV-VI quantum wires deviates from the well-known 1/3 rule together with the fact that there is a critical zone within which quenching of the diamagnetic susceptibility occurs.
