Over the past two decades, the magnetic ground states of all rare earth titanate pyrochlores have been extensively studied, with the exception of Sm$_2$Ti$_2$O$_7$. This is, in large part, due to the very high absorption cross-section of naturally-occurring samarium, which renders neutron scattering infeasible. To combat this, we have grown a large, isotopically-enriched single crystal of Sm$_2$Ti$_2$O$_7$. Using inelastic neutron scattering, we determine that the crystal field ground state for…

Intermultiplet transitions and magnetic long-range order in Sm-based pyrochlores
We present bulk and neutron scattering measurements performed on the isotopically enriched $^{154}\mathrm{Sm_2Ti_2O_7}$ and $^{154}\mathrm{Sm_2Sn_2O_7}$ samples. Both compounds display sharp heat
Quantum Spin Ice Dynamics in the Dipole-Octupole Pyrochlore Magnet Ce_{2}Zr_{2}O_{7}.
TLDR
The low-energy inelastic neutron scattering measurements show a dynamic quantum spin ice state, with suppressed scattering near |Q|=0, and no long-range order at low temperatures, consistent with recent theory predicting symmetry-enriched U(1) quantum spin liquids for such DO doublets decorating the pyrochlore lattice.
Magnetic Excitations in Quantum Rare Earth Pyrochlores
Rare-earth pyrochlores are materials with chemical formula A2B2O7, where A is the rare-earth ion and B is a transition metal. At low temperature, these systems host various magnetic states such as

Order out of a Coulomb Phase and Higgs Transition: Frustrated Transverse Interactions of Nd_{2}Zr_{2}O_{7}.
TLDR
The pyrochlore material Nd{2}Zr_{2}O_{7} with an "all-in-all-out" (AIAO) magnetic order shows novel quantum moment fragmentation with gapped flat dynamical spin ice modes and the existence of a Coulombic phase above T_{N}.

TLDR
Analytical forms for spin waves in pyrochlore magnets with dipolar-octupolar interactions, such as Nd2Zr2O7 are derived and the diagonalized magnonic Hamiltonian within the linear spin wave approximation is obtained.
