Synthesis, structure and electrical properties of Li+-doped pyrochlore Gd2Zr2O7
Chimica Techno Acta, 2020 The pyrochlore Gd1.55Li0.45Zr2O6.55 was prepared by the solution and solid-state methods. The introduction of lithium in the Gd-sublattice led to decrease in the lattice parameter a = 10.4830(8) Å in comparison with Gd2Zr2O7 (a =10.5346(2) Å). Monitoring
