Search for Emergent Photon Excitation in Pr Based Quantum Spin Ice Candidates
By introducing transvers terms in the effective spin-1/2 Hamiltonian on the pyrochlore lattice, the quantum spin ice (QSI) state, a special quantum spin liquid whose emergent... -
High resolution powder diffraction on Sm based pyrochlores
Magnetic frustration is a hot topic in solid state physics, mainly due to the topological new phases of matter that frustration mechanisms can drive (vide Physics Nobel Prize... -
Low temperature neutron diffraction of Sm2Ti2O7 pyrochlore compound
Topological phases of matter became scientific highlights during the 70's and magnetic frustration is one of the mechanisms that is believed to drive systems to one of that many... -
Are magnetic excitations in the Yb based pyrochlores really gapless?
A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even... -

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...
