An attempt is made to study the dia‐ and paramagnetic susceptibilities of electrons in quantum dots of optoelectronic materials in the presence of a parallel magnetic field, on the basis of a newly formulated electron dispersion law. It is found, taking n‐Hg 1−x Cd x Te and In 1−x Ga x As y P 1−y lattice‐matched InP as examples that both susceptibilities increase with increasing electron concentration in oscillatory manners and increase monotonically with decreasing film thickness in the electric quantum limit. In addition, the numerical values of the susceptibilities in quaternary materials are greater than in the ternary compounds.
