The pyrochlore compound Pr2Zr2O7 is very likely a "quantum spin ice" candidate, with similar physics as encountered in the celebrated Tb2Ti2O7. Recently, neutron experiments have provided new insight into the properties of the later material, and shown that a strong magneto-elastic coupling between acoustic phonons and CEF transitions is likely at play, giving rise to effective interactions between quadrupoles on the top of exchange interactions. In this context, we would like to carry out a 7 days experiment on IN5 (with the dilution fridge and a cryomagnet) to determine if similar observations and conclusions hold in the case of Pr2Zr2O7.
