“…Weak exchange interaction between thulium cations compared to the gap between singlet ground state and first excited state was reported also for the titanium counterpart: Tm 2 Ti 2 O 7 pyrochlore [49], as well as other Tm-based compounds [51,52]. The crystal-field splitting is strong enough to preclude magnetic order also in other non-Kramers ion systems, most notably Prbased systems [53][54][55][56][57][58]. However, recent neutron diffraction study on Tm 2 Mn 2 O 7 [59] revealed a magnetic signal that is not consistent with the magnetic moment only on Mn 4+ .…”

The newly synthesized Tm 2 Ir 2 O 7 iridate is investigated using neutron scattering techniques. Powder neutron diffraction patterns confirm that Tm 2 Ir 2 O 7 crystallizes in a cubic structure of pyrochlore type, consistent with the rest of the rare-earth A 2 Ir 2 O 7 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 Tm 2 Ir 2 O 7 . 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.

“…Single crystals of CeT Al 3 (T = Cu, Ag, Au, Pd and Pt) and UIrSi 3 were synthesized using optical floating zone growth [31,82]. Single crystals of CeT Si 3 (T = Co,Ir,Ru and Rh) [70,[83][84][85][86], NdCuAl 3 , PrCuAl 3 and SmCuAl 3 [34,87] were grown using the Czochralski pulling method in a tetra-arc furnace.…”

“…No magnetic ordering can occur in a singlet ground state system unless the exchange interaction exceeds the strength of the crystal electric field [93]. For example, PrCuAl 3 , PrCuGa 3 , PrCoGe 3 and PrRhSi 3 have been reported to have no magnetic ordering [87,94,97,127,135]. On the other hand, PrIrSi 3 and PrCoSi 3 exhibit a long-range magnetic order [91,93].…”

The structural and compositional diversity of the RTX 3 family of materials offers various magnetic and thermodynamic properties such as complex magnetic structure, vibronic bound states, heavy-fermions, valence fluctuations, metamagnetism, spin glass behavior, quantum criticality, and unconventional superconductivity. Here we present an overview of the crystal structures, crystal growth and magnetic properties of RTX 3 compounds as well as a discussion of the relevant physics. The magnetic properties of several compounds of the RTX 3 family still remain unexplored. The compounds with a complex magnetic structure could potentially host exotic topological phases. This review article may help in the exploration of exotic magnetic properties such as the vibron state and topological spin textures.

“…For example, EuNiGe 3 has two magnetic phase transitions at zero-field and the lowest temperature phase is believed to be a modulated phase with a constant moment 45,67 . The magnetic structures of a large number of compounds in this family of materials have not yet been determined [69][70][71][72][73] .…”
