Query: Tunneling conductance in half-metal/conical magnet/superconductor
  junctions in the adiabatic and non-adiabatic regime: self-consistent
  calculations   The tunneling conductance in the half-metal/conical magnet/superconductor
(HM/CM/SC) is investigated by the use of the combined Blonder-Tinkham-Klapwijk
(BTK) formalism and the Bogoliubov-de Gennes (BdG) equations. We show that the
conductance calculated self-consistently differs significantly from the one
calculated in the non-self-consistent framework. The use of the self-consistent
procedure ensures that the charge conservation is satisfied. Due to the spin
band separation in the HM, the conductance in the subgap region is mainly
determined by the anomalous Andreev reflection the probability of which
strongly depends on the spin transmission in the CM layer. We show that the
spin of electron injected from the HM can be transmitted through the CM to the
SC adiabatically or non-adiabatically depending on the period of the exchange
field modulation. We find that the conductance in the subgap region oscillates
as a function of the CM layer thickness wherein the oscillations transform from
irregular, in the non-adiabatic regime, to regular in the adiabatic case. In
the non-adiabatic regime the decrease of the exchange field amplitude in the CM
leads to the emergence of the conductance peak for one particular CM thickness
in agreement with experiment [J.W.A Robinson, J. D. S Witt and M. G. Blamire,
Science 329, 5987]. For both transport regimes the conductance is analyzed over
a broad range of parameters determining the spiral magnetization in the CM.
