Ferromagnetic Heusler Co2FeAl0.5Si0.5 epitaxial Tall Swivel Stool thin-films have been fabricated in the L21 structure with saturation magnetizations over 1200 emu/cm3.Andreev reflection measurements show that the spin polarization is as high as 80% in samples sputtered on unheated MgO (100) substrates and annealed at high temperatures.

However, the spin polarization Cinema Accessory is considerably smaller in samples deposited on heated substrates.
