Abstract

A variable field neutron diffraction study of the ruthenocuprate RuSr2Nd0.9Y0.2Ce0.9Cu2O10-(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.
