Magnetoresistance of self-assembled lateral multilayers

Abstract

The angular-dependent magnetoresistance and magnetization of epitaxial FeηAg1-η self-assembled lateral multilayers (SALMs) grown on Mo(110)/Al2O3(11-2 0) template layers has been examined for an optimum stoichiometry of η=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 ΔR/R of 0.88% at 2.7 K. © 2000 American Institute of Physics.
