Structure Of Metal

The role of the metal-oxide interface in determining the spin polarization of electrons tunneling from or into ferromagnetic transition metals in magnetic tunnel junctions is reported. The spin polarization of cobalt in tunnel junctions with an alumina barrier is positive, but it is negative when the barrier is strontium titanate or cerium lanthanite. The results are ascribed to bonding effects at the transition metal–barrier interface. The influence of the electronic structure of metal-oxide interfaces on the spin polarization raises interesting fundamental problems and opens new ways to optimize the magnetoresistance of tunnel junctions.

The Impact

We present magnetoresistance (MR) measurements on two unique granular ferromagnetic geometries: nanosized granular systems and magnetic tunnel junctions employing a granular electrode. In both systems the saturation fields of the magnetoresistance as well as the MR magnitudes are much larger than that of usual granular films. We interpret these results as being due to the impact of ultrasmall grains. The presence of such nanograins in a random granular array is usually undetectable since their influence on transport, magnetization and magnetoresistance is negligible. Our samples emphasize the role played by these grains leading to a number of unique effects and potential applications.
