Abstract

Copper-divanadate Cu2-yZnyV2O7 comprises trans-edge sharing chains of
CuO5 polyhedra where Cu spins S = 1/2 are antiferromagnetically
coupled. Zn substitution for Cu induces a structural phase transition
which affects strongly the magnetic properties. In particular, a
substantial magnetic anisotropy found in one of the structural phases
is strongly suppressed in the other one, owing to the changes of the
local bonding geometry. (C) 2003 Elsevier B.V. All rights reserved.
