The pyrochlores provide an excellent model system for studying the interaction of framework vibrational modes, defects and magnetism. We propose to investigate these couplings...

Crystal Structure of Yb2Ti2O7 pyrochlores

Pyrochlores A2B2O7, a superstructure of defect fluorite (A,B)O1.75, allow a wide range of cations to be introduced both to A and B sites. This remarkable tolerance to chemical...

Structural distortions at low temperature on the pyrochlore Yb2Ti2O7

Magnetic frustration occurs when nearest-neighbor competing interactions cannot be simultaneously satisfied. Pyrochlores, whose crystalline lattices form corner-sharing...
