Abstract
The Andreev reflection probability for a
ferromagnet/isolator/superconductor (FIS) contact at the arbitrary
spin-dependent amplitudes of the electron waves transmitted
through and reflected from the potential barrier is found. It is
shown that Andreev reflection probabilities of electron and hole
excitations in the FIS contact are different. The energy levels of
Andreev bound states are found. The ballistic conductance of the
point FIS contact is calculated.
