We have studied the influence of Ce-doping upon local properties at Gd site
s in Gd1-xCexCu6 by Gd-155 Mossbauer spectroscopy. Our primary interest con
centrated upon the evolution of the magnetic order of Gd moments and of the
electronic density at Gd sites with increasing Ce-concentration. In additi
on, the variation of magnetic hyperfine fields with temperature yields esti
mates of the Neel temperature as a function of Ce content x. (C) 2000 Elsev
