Abstract
The magnetic tunneling effect has been investigated for Fe/Al-oxide/Fe junctions to clarify the relationship between magnetoresistance (MR) ratio and barrier height of ferromagnetic tunneling junctions. The MR ratio measured at 4.2 K and 0.5 mV varied from about 0.5% to 30% depen ding on barrier height. The barrier height dependence of MR ratio at 4 .2 K was roughly the same as that of Slonczewski's calculation. (C) 19 98 Elsevier Science B.V. All rights reserved.
