摘要: Polycrystalline Sr 2Fe 1-xAl xMoO 6 samples have been prepared by solid-state reaction . Magnetic measurements show that this substitution induces a significant d rop in the Curie temperature correlates with t he Al concentration. We decrease increasing concentration can be interpreted terms of 3D random site dilution. The magneto-resistance at liq uid helium and up to 12 T has measured pure compound where close 30 % is found, electronic spin polarization es timated 65 low temperatures.
