A ug 2 00 3 Magnetic Order and Dynamics in Stripe-Ordered La 2 − x Sr x NiO 4

Abstract

We have studied magnetic correlations in several compositions of stripe-ordered La2−xSrxNiO4. In this paper we show how polarized-neutron scattering has helped uncover important features of the magnetic ordering and spin dynamics. In particular, polarization analysis has enabled us (1) to characterize a spin reorientation transition, (2) to identify… (More)
