Field Dependent Neutron Scattering Studies of Breathing Pyrochlore Ba<sub>3</sub>Yb<sub>2</sub>Zn<sub>5</sub>O<sub>11</sub>

Abstract

Breathing pyrochlore systems are composed of corner-sharing tetrahedra of different sizes pointing in opposing directions, leading to different intra- and inter-tetrahedra exchange interactions and the emergence of the Dzyaloshinskii-Moriya interaction due to loss of inversion symmetry. They are predicted to host exotic physics including quantum spin ice, quantum spin liquid, and field-tunable Weyl magnons. In this talk we will present single-crystal field-dependent unpolarized and polarized inelastic neutron scattering measurements on Yb-based breathing pyrochlore system, as well as a theoretical model that can effectively describe some of our experimental findings.
