Magnetoresistance Of Self-Assembled Lateral Multilayers

The angular-dependent magnetoresistance and magnetization of epitaxial FeetaAg1-eta self-assembled lateral multilayers (SALMs) grown on Mo(110)/Al2O3(11-2 0) template layers has been examined for an optimum stoichiometry of eta=0.38. The low-temperature anisotropic magnetoresistance (AMR) and low-field magnetoresistance (MR) are measured as a function of field angle for two nearly orthogonal current directions. The SALM structures are observed to display a significant AMR (roughly 1.6% maximum for the entire structure) and a pronounced field-dependent MR with a maximum Delta R/R of 0.88% at 2.7 K.
