Abstract
The dependence of the magnetoresistance ratio, Delta R/R(s), on the Ni content has been studied in Fe/Al2O3/Ni1-xFex (0 less than or equal t o x less than or equal to 1) tunneling junctions. The value of Delta R /R(s) at 4.2 K increased with increasing x and exhibited a maximum of similar to 35% at x = 0.8. The result is discussed by taking into acco unt the spin-polarization of ferromagnetic electrodes. (C) 1996 Americ an Institute of Physics.
