Magnetic diffuse neutron scattering study on quantum spin liquid candidate Ba4NbIr3O12.
A new Iridate material Ba4NbIr3O12 has been reported to be a quantum spin liquid (QSL) candidate very recently based on macroscopic thermodynamic measurements. In this frustrated oxide, no long-range magnetic order is observed down to 360 mK. In addition, a low temperature linear behaviour in the specific-heat data strongly advocates for a possible quantum spin-liquid ground state. A frustration parameter of larger than 37 strengthens the possibility of having a quantum spin liquid state furthermore. To observe microscopic evidence of the QSL state, we propose to perform magnetic diffuse scattering experiment with polarized neutron and XYZ polarization analysis on the powder sample. To ensure the quantum behaviour, we propose to perform this measurement in the mK regime using a dilution refrigerator cryostat. This experiment will provide us information about the temperature dependence of the short-range magnetic order, a very important signature in the context of QSL physics. We will also do model calculations with the experimental data to have quantitative idea of the spin Hamiltonian.
