Giant Magnetoresistance by Exchange Springs in DyFe${}_2$/YFe${}_2$ Superlattices

S. N. Gordeev, J-M. L. Beaujour, G. J. Bowden +5

Magnetization and magnetoresistance measurements are reported for antiferromagnetically coupled DyFe${}_2$/YFe${}_2$ multilayers in fields up to 23 T. We demonstrate that the formation…
