Abstract

A new ruthenocuprate Pb2Sr2Cu2RuO8Cl has been synthesised in a mixed phase sample. It has a tetragonal unit cell, space group P4/mmm (a = 3.86681(9), c = 15.3699(8) Angstrom). A neutron diffraction study has been performed at 295 and 10 K, which reveals that the average crystal structure is tetragonal with no evidence of superstructure or orthorhombic distortion. Antiferromagnetic diffraction peaks are observed in the 10 K neutron diffraction pattern but weak ferromagnetism below T-M = 117 K is evidenced from DC magnetometry experiments. The magnetism of this material appears to be strikingly similar to that of the compound RuSr2GdCu2O8. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
