Low temperature and high pressure Raman and x-ray studies of pyrochlore Tb${}_2$Ti${}_2$O${}_7$ : phonon anomalies and possible phase transition

Surajit Saha, D. V. S Muthu, Surjeet Singh +8

We have carried out temperature and pressure-dependent Raman and x-ray measurements on single crystals of Tb${}_2$Ti${}_2$O${}_7$. We attribute the observed anomalous temperature depende…
