room temperature figure of merit) we set $T=20 \, K$ in all calculated quantities. Using the semiclassical Boltzmann approach, we investigate the electrical conductivity, Seebeck coefficient ($\mathcal{S}$), and its corresponding figure of merit ${\it ZT}$, considering the various types of resistive scattering potential, such as (1) the short-range potential, (2) long-range charge-charge Coulomb potential, with a Thomas- Fermi screening as the source of scattering and (3) impurities containing short-range electric and ferromagnetically ordered magnetic potentials, the electro-magnetic scatterers. It is important to emphasize that this semiclassical theory is valid only in a dilute impurity concentration regime [*i.e.*]{} when the impurities concentration is much smaller than the charge carriers concentration. Moreover, to ensure that the diluteness criteria is satisfied, the impurities concentration $n_{{\rm imp}}=10^{10}{\rm m^{-2}}$ (corresponding to the chemical potential of approximately $\mu\sim3\times10^{-8}~e{\rm V}$), is considered.

It is worthwhile to mention that the other essential criteria for utilizing the Boltzmann equation are as follows: Particles might interact via binary collisions, impurity density is low in terms of the charge carriers, external fields might have short-range frequencies and all collisions are elastic and involve only uncorrelated particles. Here, we notice that using the lattice symmetry, the orientations of the two principal lattice
