Spin dynamics in Pr2Zr2O7: interplay of quadrupolar and dipolar degrees of freedom in spin ice
The proposed experiment is part of our systematic experimental studies of geometrical frustration in various pyrochlore R2M2O7 (R = Rare earth, M an element like Ti, Sn, Zr). Here, we propose to study the spin excitations in Pr2Zr2O7 for H//111 at IN5. In combination with our previous measurements, this new dataset would provide a complete study of non-Kramers rare earth (like Pr) based pyrochlore which are likely governed by dominant effective coupling between quadrupoles on top of weaker interactions between dipoles. This experiment would stand as a test of our scenario.
