Understanding magnetic properties of the Breathing Pyrochlore Material Ba<sub>3</sub>Yb<sub>2</sub>Zn<sub>5</sub>O<sub>11</sub>

ORAL

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. Ba3Yb2Zn5O11 is unique among breathing pyrochlore compounds for being in the nearly decoupled limit, where inter-tetrahedra interactions are weak. In this talk, we will discuss the magnetic properties in this material and present our results collected on a single crystal sample. We will discuss the features that agree with the single tetrahedron model and a possible scenario for the deviation of the experimental observation from the single tetrahedron model.
