Pyrochlore magnets are one of the cornerstones of frustrated magnetism, with two interpenetrating lattices of corner-sharing tetrahedra on which magnetic ions can be placed. By changing the ions on the A and B sites considerable changes in their physical properties can be realized. Here we propose to investigate the newly synthesized pyrochlore Bi2Ir2O7, which are Ir4+ S=1/2 magnetic moments, shows no evidence for long-range magnetic ordering down to dilution fridge temperatures, yet suggests that a cooperative paramagnetic state emerges below around 40K. Our measurements will search for any weak and hitherto undiscovered magnetic ordering, probe the magnetic fluctuations, and test for instabilities to order in applied magnetic fields.
