  The finding of a new formulation of the magnetization vector of a quantum
system interacting with a static uniform magnetic field\cite{Selenu1} is
reported. There a gauge invariant form of its divergence is shown being
expressed as a function of the electronic current per state coupled with the
Berry curvature of the quantum system. A Fourier analysis of the magnetization
vector and magnetization density is reported as an application of the presented
formula it could be applied in the context of computational
modelling\cite{Martin} of quantum matter.
