Abstract
Room temperature X-ray diffraction shows that Gd1-xNdxCu compounds crystall ize either in the CsCl or in the FeB orthorhombic structure, which show dif ferent magnetic properties. Thermal expansion measurements show that these compounds undergo a structural transition, which takes place by a martensit ic transformation. The existence of electronic states with different total energy can explain the observed structural instability. (C) 1999 Elsevier S cience B.V. All rights reserved.
