Determination of crystal field spectrum in terbium gallium garnet.
Magnetic frustration is the phenomenon resulting from inability to satisfy all magnetic interactions present in a system. It has drawn lots of attention as it is the source of... -
Tunable algebraic correlations and Kasteleyn transition in kagome ice
We propose to continue our search for the Kasteleyn transition in the kagome ice phase of the spin ice Ho2Ti2O7. The experiment requires the applied magnetic field to be... -
Quasielastic scattering in stuffed spin ices: defects or low lying singlets?
The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very... -
Quantum Spin Ice ground states and Structural Disorder in non-Kramers rare-ea...
Pyrochlore oxides based on non-Kramers rare-earth ions, such as Pr3+ and Tb3+, are candidate materials for the formation of the Quantum Spin Ice. However, structural disorder is... -
Do defect structures in the pyrochlore Tb2Ti2O7 control hidden order or the t...
The rare earth pyrochlores have been at the forefront of research into exotic magnetic phenomena for some years. In general they are of interest because they are frustrated -... -
Nature of the ground state of Dy2Ti2O7 spin ice
Spin ice (SI) is a state of matter characterized by a residual (Pauling) entropy and unusual correlations. The huge interest in SI materials from the magnetism community stems... -
Determining Microscopic Origins of the Thermal Hall Effect in Tb2Ti2O7
Studies of thermal Hall effects in insulating materials ascribe its microscopic origins to charge-neutral bosonic carriers generated by non-zero Berry curvature in the... -

Magnetic Charge Transport in Spin Ice
The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored... -
Hidden Correlations in CeSn2O7
In the pyrochlore magnet Ce2Sn2O7, we have established that a correlated disordered ground state develops below about 0.6 K, and that the Ce3+ magnetic ions have both dipole and... -
Crystal electric field excitations of pyrochlore quantum antiferromagnet Ce2S...
We have recently discovered an exotic magnetic state developing at subKelvin temperatures in the Ce3+ pyrochlore stannate. The spin system of this compound is characterized by a... -
Single Crystal Scattering Study of 163-Dy2Ti2O7 Using SXD
Spin ice materials are a class of compounds with exotic magnetic properties, resulting from the frustration. Magnetic monopoles have been detected at low temperature; manifest... -
The search for magnetic monopoles in spin ice.
In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist... -
Phonon dispersions in the magnetoelastic spin liquid Tb2Ti2O7 and spin ice Ho...
We plan to measure the phonon dispersions of the rare earth pyrochlores Tb2Ti2O7 and Ho2Ti2O7 in their spin liquid and spin ice phases respectively. Magnetoelastic effects are...
