Opis:: Electronic transport in a nanoscopic magnetic tunnel junction with magnetic particles or magnetic impurity atoms/molecules embedded in the barrier is studied theoretically. The impurity Hamiltonian includes magnetic anisotropy of easy axis type with additional perpendicular term. The description takes into account both elastic tunneling processes as well as inelastic processes associated with a flip of electron spin.

Opis:: The effect of transverse magnetic anisotropy on spin-dependent transport through a large-spin molecule strongly tunnel-coupled to ferromagnetic electrodes is analyzed theoretically. In particular, we investigate whether it is possible to observe in transport signatures of oscillations of the ground-state doublet splitting due to the application of an external magnetic field along the molecule's hard axis. We show that magnetic field leads to revivals of the Kondo effect, with the Kondo temperature depending on the magnetic configuration of the device.

Opis:: Spin Hall effect in a two-dimensional electron gas with uniform Dresselhaus and random Rashba spin-orbit interactions is considered theoretically. Using Kubo formalism we derive some analytical formula for the spin Hall conductivity. It is shown that the contribution due to randomly fluctuating Rashba field disappears in the limit of strong Dresselhaus coupling.
