Query: Spin-dependent thermoelectric effects in transport through a nanoscopic
  junction involving spin impurity   Conventional and spin-related thermoelectric effects in transport through a
magnetic tunnel junction with a large-spin impurity, such as a magnetic
molecule or atom, embedded into the corresponding barrier are studied
theoretically in the linear-response regime. The impurity is described by the
giant spin Hamiltonian, with both uniaxial and transverse magnetic anisotropy
taken into account. Owing to the presence of transverse component of magnetic
anisotropy, spin of a tunneling electron can be reversed during scattering on
the impurity, even in the low temperature regime. This reversal appears due to
exchange interaction of tunneling electrons with the magnetic impurity. We
calculate Seebeck and spin Seebeck coefficients, and analyze their dependence
on various parameters of the spin impurity and tunnel junction. In addition,
conventional and spin figures of merit, as well as the electronic contribution
to heat conductance are considered. We also show that pure spin current can be
driven by a spin bias applied to the junction with spin impurity, even if no
electron transfer between the electrodes can take place. The underlying
mechanism employs single-electrode tunneling processes (electrode-spin exchange
interaction) and the impurity as an intermediate reservoir of angular momentum.
