Magnetoresistance of Multilayers Prepared on Microstructured Substrates

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% for the current perpendicular to the grooves and 8.1% for the current parallel to the grooves at room temperature.
