We now fix t LR = 0.01 and the angle φ = π/ 2, i.e., the magnetic moments of the leads are perpendicular to each other, to examine the bias dependence of these quantities for different values of leads' polarization P L = P R = P.
Figure 3 Tunneling current, current polarization and TMR each as a function of the bias voltage for different values of leads' polarization and fixed φ = π/ 2. The other parameters are as in Fig. 2. Finally we study how the inter-lead coupling strength t LR influence these quantities.
We analyze a quantum dot attached to both a ferromagnetic lead with polarization p L =p and a normal lead with polarization p R =0.
The lack of functional or legitimate political institutions, weak economic performance, a nonexistent or polarized structure of civil society, and antagonized elites lead to polarization and separation, leaving societies deeply divided and prone to further ethnic strife.
He urged parishioners to seek "balance" and to be wary of "extreme" positions on both sides of the issue, which he said lead to "polarization".
At worst, according to Hawley, the long-term costs of expansion would lead to polarization and inequality, urban decay, environmental destruction, and political instability, which over time must result in a reordering of the ecosystem.
At scale it can undermine the quality of public discourse and lead to polarization.
It is well known that the lacking of center symmetry in ZnO lead ionic polarization can be induced by strain [29].
Inhomogeneities in the ionospheric conductivity can lead to polarization electic fields and secondary ionospheric currents which can reinforce primary currents forming electrojets.
Fiber movement can lead to polarization state changes and thereby corrupt the measurement.
