abstract = {Pyrochlore and defect fluorite (Eu1−xNdx)2Zr2O7 compounds
(x = 0, 0.5 and 0.75) synthesized by a wet chemicalapproach
were investigated using temperature dependent high energy
X-ray diffraction as well as 151Eu Mössbauerspectroscopy.
Diffraction data reveals an increase in lattice parameter
with increasing Nd content, an increase thatis
disproportionally large between x = 0.5 and 0.75. The 151Eu
Mössbauer spectral parameters, i.e. isomer shift
andquadrupole splitting, fall in separate regions for
pyrochlore and defect fluorite type compounds. Between 80 -
350 K,the impact of the order-disorder, i.e. pyrochlore to
defect fluorite, transition on isomer shift and quadrupole
splittingis found to exceed the one due to lattice
expansion.},
