Abstract

The metal–insulator transition in GdBaCo2O5:5 at TMIE360 K has been investigated by synchrotron X-ray powder diffraction and magnetic measurements. We have found that,at TMI remarkable structural distortions and magnetic changes take place. These changes evidence a spin state transition of Co ions at this temperature that is the origin of the metal–insulator transition. r 2002 Elsevier Science B.V. All rights reserved.
