Recently a new class of quantum magnets, the so-called breathing pyrochlore systems, have attracted much attention due to their potential to host exotic emergent phenomena. Here, we present magnetometry, thermal, muon-spin relaxation, and polarized inelastic neutron scattering measurements performed on high-quality single-crystal samples of breathing pyrochlore compound Ba3Yb2Zn5O11. We interpret these results using a simplified toy model and provide a new insight into the low-energy physics of this system beyond the single-tetrahedron physics proposed previously.
