Description:
F-I-S tunnel junctions of Co 2 CrAl-I-Pb and Co 2 Cr 0.6 Fe 0.4 Al-I-Pb based on films of semimetal ferromagnetic Heusler alloys Co 2 CrAl (Curie temperature T C ≈ 334 K) have been fabricated and the features of spin-polarized current in them studied. A theoretical model of spin blocking of the tunnel current shows that the degree of spin polarization of the conduction electrons in quasi-single crystal films of Co 2 Cr 0.6 Fe 0.4 Al and Co 2 CrAl with B 2- and L 2 1 -type order is 0.91–0.97.
