Abstract

Direct measurement of the spin polarization (P) of the magnetic semiconductor Ga_1-xMn_xAs was carried out using Andreev reflection spectroscopy. The conductance spectra of high transparency junction showed an intrinsic value for P greater than 85%. Results showed an extreme sensitivity of the measured spin polarization to the nature and quality of the interface for the material.
