Magnetoelastic excitations in the pyrochlore spin liquid Tb${}_2$Ti${}_2$O${}_7$

T. Fennell, M. Kenzelmann, B. Roessli +9

At low temperatures, Tb${}_2$Ti${}_2$O${}_7$ enters a spin liquid state, despite expectations of magnetic order and/or a structural distortion. Using neutron scattering, we have discover…
