Spin and charge transport in a magnetic tunnel junction with magnetic impurities embedded in the tunnel barrier

Artikel i vetenskaplig tidskrift, 2015

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.
