- Abstract
The structural and magnetic properties of TlCo(2-x)Cu(x)Se2 have been investigated experimentally. The antiferromagnetic coupling already found in TlCo2Se2 prevails on copper substitution but is weakened. For high copper contents, x larger tahn 1.3, Pauli paramagnetism occurs. -- The magnetic structure of teh unsubstituted TlCo2Se2 has been reinvestigated by neutron powder diffraction. Below 80K it is characterised by a helimagnetic arrangement of spins confined to the Co sheets, the helix running along the c-axis., DEPT OF MATERIALS CHEMISTRY, UPPSALA UNIVERSITY, BOX 538, SE-751 21 UPPSALA; DEPT OF MATERIALS SCIENCE, UU, BOX 534, SE-751 21 UPPSALA; LABORATOIRE DE CHIMIE DU SOLIDE MINERAL, BP VANDOEVRE LES NANCY, FRANCE
