Abstract

Magnetization and neutron-diffraction measurements have been performed on single crystals of Ba2Cu3O4Cl2 and Sr2Cu3O4Cl2, isomorphous layered insulating cuprates containing two types of Cu-site in the Cu3O4 planes. Neutron-diffraction measurements revealed both three-dimensional antiferromagnetic order of Cu2+ spins on one of the sites (A-site), which are connected by the Cu(A){single bond}O{single bond}Cu(A) 180°-bonds, and successive order of the other site (B-site), which locates at the centre of the Cu(A)O2 square. Magnetization measurements indicate an in-plane weak ferromagnetic moment below the Néel temperature TN due to spin canting within the Cu3O4 planes.
