Phonon thermal Hall effect in non-magnetic Y${}_2$Ti${}_2$O${}_7$

Rohit Sharma, Martin Valldor, Thomas Lorenz

We report an investigation of the phonon thermal Hall effect in single crystal samples of Y${}_2$Ti${}_2$O${}_7$, Dy${}_2$Ti${}_2$O${}_7$, and DyYTi${}_2$O${}_7$. We measured the field-linear ther…
