  The ground state properties of a high spin magnetic impurity and its
interaction with an electronic spin are probed via Andreev reflection. We see
that through the charge and spin conductance one can effectively estimate the
interaction strength, the ground state spin and magnetic moment of any high
spin magnetic impurity. We show how a high spin magnetic impurity at the
junction between a normal metal and superconductor can contribute to
superconducting spintronics applications. Particularly, while spin conductance
is absent below the gap for Ferromagnet-Insulator-Superconductor junctions we
show that in the case of a Normal metal-High spin magnetic impurity-Normal
Metal-Insulator-Superconductor (NMNIS) junction it is present. Further, it is
seen that pure spin conduction can exist without any accompanying charge
conduction in the NMNIS junction.
