We have fabricated nanoscale magnetic tunnel junctions (MTJs) with anadditional fixed magnetic layer added above the magnetic free layer of astandard MTJ structure. This acts as a second source of spin-polarizedelectrons that, depending on the relative alignment of the two fixed layers,either augments or diminishes the net spin-torque exerted on the free layer.The compound structure allows a quantitative comparison of spin-torque fromtunneling electrons and from electrons passing through metallic spacer layers,as well as analysis of Joule selfheating effects. This has significance forcurrent-switched magnetic random access memory (MRAM), where spin torque isexploited, and for magnetic sensing, where spin torque is detrimental.Comment: 3 pages, 2 figures, to appear in Appl. Phys. Let
