Magnetoresistance of Multilayers Prepared on Microstructured Substrates

Abstract

A new class of multilayers was prepared by using substrates with V-groove micro-structures. The magnetoresistance ratio of a sample [Cu(58, Å)/Co(12, Å)/Cu(58, Å)/NiFe(12, Å)]× 180 fabricated on a substrate with a V-groove period of 2, μ m shows a large anisotropy; 12⊥endicular to the grooves and 8.1→ the grooves at room temperature.
