WebFeb 14, 2024 · Herein, the structure and magnetic properties of the breathing pyrochlore compound LiInCr 4−x Fe x O 8 (x = 0, 0.2, 0.4, 0.5) are reported. Raman scattering experiments show the hardening behavior of the active mode induced by the increased ionic masses and bond strength. WebOct 16, 2024 · The breathing pyrochlore lattice material Ba 3 Yb 2 Zn 5 O 11 exists in the nearly decoupled limit, in contrast to most other well-studied breathing pyrochlore compounds. As a result, it constitutes a useful platform to benchmark theoretical calculations of exchange interactions in insulating Yb 3+ magnets.
