Magnetic phase diagram under pressure of Ho and Nd pyrochlore iridates
In pyrochlore iridates (formula R2Ir2O7), the iridium magnetic moments apply a molecular field on the rare-earth ions, resulting in a wide variety of magnetic phases. Recently, a theoretical phase diagram was computed, showing that by varying the Ir molecular field and the rare-earth interactions, one can go from an antiferromagnetic state to a fragmented phase (where the magnetic moment fragments into an ordered antiferromagnetic phase and a fluctuating phase) and to a spin ice state. We propose to explore this phase diagram experimentally by measuring the magnetic structure under pressure in Ho2Ir2O7, where we have shown the existence of a fragmented phase, and in Nd2Ir2O7, where the published and our preliminary results suggest that the compound is close to a phase boundary.
