Title: Structural and magnetization behavior of highly spin polarized Co{sub 2}CrAl full Heusler alloy

The half metallic ferromagnet Co{sub 2}CrAl full Huesler alloy was successfully prepared by arc melting process. The electrical and magnetic properties of Co{sub 2}CrAl alloy have been studied in the temperature range of 5 – 300 K. The ferromagnetic Curie temperature T{sub c} of the same alloy has been observed at 329.8 K. The alloy shows semiconducting like electronic transport behavior throughout the studied temperature range. The origin of the semiconducting behavior of Co{sub 2}CrAl alloy can be best explained by the localization of conduction electrons and the presence of an energy gap in the electronic spectrum near the Fermi level E{sub F}.
