Abstract

A variable field neutron diffraction study of the ruthenocuprate RuSr₂Nd_0.9Y_0.2Ce_0.9Cu₂O_10-(delta) which exhibits large negative magnetoresistance, has been performed in order to determine the variation of the magnetic structure with magnetic field. Upon application of a magnetic field the (1/2 1/2 1/2) and (1/2 1/2 l) magnetic peaks reduce in intensity as the spins in the RuO₂ and CuO₂ layer cant into a ferromagnetic alignment in theab-plane. This results in increased spin polarised transport in the CuO₂ plane and hence large negative magnetoresistance. (c) 2006 Elsevier B.V. All rights reserved.
