Popis:	We have studied the temperature-dependent and barrier-strength-dependent Andreev reflection tunnelling spectroscopy with point contacts consisting of the newly synthesized half-metallic alloy NiFeSb and a Nb tip. By fitting the data to the generalized Blonder-Tinkham-Klapwijk theory, a spin polarization P = 0.52 has been obtained.
