The non-stationary response of local magnetic moment to abrupt switching ‘‘on” and ‘‘off” of external
magnetic field was studied for a single-level quantum dot (QD) coupled to a reservoir. We found that
transient processes look different for the shallow and deep localized energy level. It was demonstrated
that for deep energy level the relaxation rates of the local magnetic moment strongly differ in the case
of magnetic field switching ‘‘on” or ‘‘off”. Obtained results can be applied in the area of dynamic memory
devices stabilization in the presence of magnetic field
