Title: Neutron-scattering study of magnetism in Nd[sub 2]BaNiO[sub 5]

Abstract

Single crystals of the linear chain phase Nd[sub 2]BaNiO[sub 5+[delta]] [[delta]=0.005(1)] have been prepared and the magnetism studied by neutron scattering. The Ni-O chain direction is along the short axis [ital a]. Long-range antiferromagnetic order sets in below [ital T][sub [ital N]]=48 K with Nd and Ni moments parallel to [001]. The Nd[sub 2]BaNiO[sub 5] magnetic cell is doubled along [ital a] and [ital c] relative to the chemical unit cell. The magnitude of the moments at 4.9 K is 2.7(2) and 1.2(1)[mu][sub [ital B]] for Nd and Ni, respectively.
