Neutron scattering study of the Tm2Ir2 O7 pyrochlore iridate
Original language description
The newly synthesized Tm2Ir2O7 iridate is investigated using neutron scattering techniques. Powder neutron diffraction patterns confirm that Tm2Ir2O7 crystallizes in a cubic structure of pyrochlore type, consistent with the rest of the rare-earth A2Ir2O7 series, and the crystal structure is preserved down to 0.2 K. The thermal expansion of the crystal lattice is well described by a Debye model of lattice vibrations. A weak magnetic signal consistent with the so-called all-in-all-out magnetic order (AIAO) is traced at low temperature; however, it cannot serve as unambiguous evidence of the AIAO structure in the compound. Nondispersive magnetic excitations in energy-momentum space are observed in inelastic neutron scattering spectra of Tm2Ir2O7. The crystal-field scheme and parameters of the thulium iridate are refined and discussed with respect to the specific heat and magnetization data. The results are supported by mean-field calculations.
