Neutron Diffraction Study of the Magnetic Structure of Sr&sub(2)FeMoO&sub(6-*s) : Abstract / V.Sikolenko, V.Efimov, [a.o.] // Физика элементарных частиц и атомного ядра. Письма. – 2025. – Т. 22, № 5. – P. 1078. – URL: https://www1.jinr.ru/Pepan_letters/panl_2025_5/72_Sikolenko_ann.pdf.

Neutron diffraction study of Sr&sub(2)FeMoO&sub(6−*s) ceramic with double perovskite structure and different amount of cation superstructure ordering has been performed in a wide temperature range. Molybdenum–oxygen octahedrons remain stable for the most ordered sample with an increase in temperature, whereas samples with lower superstructure ordering demonstrate high temperature distortions. Iron–oxygen octahedron is always symmetric for the most ordered sample but more distorted for less superstructure ordered compounds. A temperature increase above Curie temperature leads to an increase in Mo–O distortions. The magnetic structure consists of Fe ions ferromagnetically ordered in bc plane and Mo ions ferromagnetically ordered in ac plane.
