We have investigated the dependence of the crystal structure of the electrode on tunnel magnetoresistance (TMR) in magnetic tunnel junctions (MTJs) using a Co2(Cr1-xFex)Al (x = 0.4, 1) electrode. The TMR for x = 1 and 0.4 are respective larger and smaller for the A2 structure than the B2 structure, which is consistent with the calculated spin polarizations. The maximum TMR of 48% is obtained at room temperature (RT) for the MTJ with the A2 type Co2FeAl electrode. However, the TMR for the B2 type Co2(Cr0.6Fe0.4)Al-based MTJ is much smaller than the value expected from the spin polarization. This reduction of the TMR for x = 0.4 might be due to the Co-Cr type atomic site disordering involving in the B2 structure.
