Neutron Scattering Studies of new RE Breathing Pyrochlore compound: Ba3Tm2Zn5O11

Breathing Pyrochlore materials have emerged as a promising candidate to study frustrated magnetism and topological phenomena, such as Weyl and Dirac magnons. We have synthesized a new member in the rare-earth based family of Breathing Pyrochlore compounds: Ba₃Tm₂Zn₅O₁₁. We have grown the single crystal of this compound. We have characterized its thermodynamic properties, which show no sign of ordering down to the lowest accessible temperature. Further, we have performed inelastic neutron scattering on single crystals to study the low-energy magnetic excitations. We have also performed high-resolution neutron diffraction at multiple fields and temperatures to study the field-driven transitions. In this talk, we are going to present our latest experimental results for this new member of the RE-based breathing pyrochlore compound Ba₃Tm₂Zn₅O_11.
