Anomalous lattice specific heat and rattling phonon modes in quadruple perovskites

Valentin Yu. Irkhin, Zhehong Liu, Danil A. Myakotnikov +3

Experimental data on the specific heat $C_{p}$ of quadruple perovskites ACu $_{3}$ Fe $_{2}$ Re $_{2}$ O $_{12}$ (A = Mn, Cu, La, Ce, Dy) are presented, demonstrating an anomalous concave-down $C…

Exchange interaction in ACu3Fe2Re2O12 quadruple perovskites

Fedor Temnikov, Alexey V. Ushakov, Evgenia V. Komleva +4

Quadruple perovskites ACu $_{3}$ Fe $_{2}$ Re $_{2}$ O $_{12}$ attract considerable interest due to their high Curie temperatures (up to $710$ K), which strongly depend on the A-site cation. In…
