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 of quadruple perovskites ACuFeReO (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 ACuFeReO attract considerable interest due to their high Curie temperatures (up to K), which strongly depend on the A-site cation. In…
Mechanism of ferromagnetic ordering of the Mn chains in CaMnGeO clinopyroxene
F. V. Temnikov, E. V. Komleva, Z. V. Pchelkina +1
The electronic and magnetic properties of clinopyroxene CaMnGeO were studied using density function calculations within the GGA+U approximation. It is shown that anomalous…
Raman spectroscopy of the low dimensional antiferromagnet with large Neel temperature SrRu2O6
Yu. S. Ponosov, E. V. Komleva, D. A. Zamyatin +2
We report results of the Raman measurements for SrRuO having extraordinary high Nel temperature for a layered material. No additional phonon modes were…
