Large Magnetoresistance of Field-Induced Giant Ferrimagnetic Multilayers

This is the authors' abstract. We don't add key points for this paper.

Multilayers consisting of two magnetic components with different anisotropies were prepared by successively depositing Co, Cu, Ni 80 Fe 20 and Cu layers. By applying a moderate field, the two magnetizations are oriented antiparallel with each other, and then the electric resistance significantly increases due to spin-dependent electron scattering. A large magnetoresistance change, 9.9% at 300 K, was observed in [Co(30 Å)/Cu(50 Å)/NiFe(30 Å)/Cu(50 Å)]×15.
