We use neutron scattering to show that ferromagnetism and antiferromagnetism coexist in
the low T state of the pyrochlore quantum magnet Yb 2 Ti 2 O 7. While magnetic Bragg …

Inelastic scattering experiments are key methods for map** the full dispersion of
fundamental excitations of solids in the ground as well as nonequilibrium states. A …

Disorder is important in the study of quantum spin liquids, but its role on the spin dynamics
remains elusive. Here, we explore the disorder effect by investigating the magnetic-field …

The frustrated rare-earth pyrochlore Yb 2 Ti 2 O 7 is remarkable among magnetic materials:
despite a ferromagnetically ordered ground state it exhibits a broad, nearly gapless …

The upconversion luminescence (UCL) nanofibers with low dimensional structure have
attracted increasing attention in recent years. It is known that oxides based UCL family …
