Abstract
The influence of the spin-dependent phase shifts (SDPSs) associated with the electronicreflection and transmission amplitudes acquired by electrons upon scattering at thepotential barrier on the Andreev reflection probability of electron and hole excitations for aferromagnet/isolator/d-wave superconductor (FIS) contact and on the charge conductanceof the FIS contact is studied. Various superconductor orientations are considered. It hasbeen found that for strong ferromagnets and ultrathin interface potential for the{110} oriented d-wave superconductor the presence of the SDPS can lead to the appearance of finite-voltagepeaks in the charge conductance of the F/I/d-wave superconductor contact. On the contrary, for the{100} orientation of the d-wave superconductor the presence of the SDPS can lead to restorationof the zero-voltage peak and suppression of finite-voltage peaks. The spin-dependentamplitudes of the Andreev reflection probability and energy levels of the spin-dependentAndreev bound states are found.
