Title: Giant magnetoresistance in actinide systems

Abstract

In contrast to ferromagnetic uranium intermetallics, which exhibit large drop below the ordering temperature, the resistivities of uranium antiferromagnets stay at much larger values below T{sub N}. In this contribution, the authors demonstrate that a large portion of the residual resistance of uranium antiferromagnets can be removed by driving the compounds through metamagnetic transition to a field-aligned state. The consequence is the field-induced drop of resistance, which can exceed {Delta}{rho}/{rho}(0T) = 90%.
