Abstract In this article, we present the structural and magnetic studies of pristine SmFeO3 nanocrystalline ceramic samples as sintered at temperature 850 °C and 1000 °C. X-ray powder diffraction data confirm the existence of single-phase nature with orthorhombic (Pbnm) structure of the samples. The SEM image reveals spherical particles with a size range of 60–130 nm for SFO-850 and SFO-1000 samples. X-ray absorption spectroscopy studies on Fe L3,2 and O K-edges of SmFeO3 sample revealed the homo-valence state of Fe in these materials. From magnetization studies it has been observed the materials exhibit ferromagnetic and antiferromagnetic (canted spin structure) sub-lattices, which results strong magnetic anisotropy in the system.

纳米晶钙钛矿结构SmFeO 3 正铁氧体的晶体学和磁学性能

摘要 在本文中,我们介绍了在 850 °C 和 1000 °C 下烧结的原始 SmFeO3 纳米晶陶瓷样品的结构和磁性研究。X 射线粉末衍射数据证实了样品具有正交 (Pbnm) 结构的单相性质。SEM 图像显示了 SFO-850 和 SFO-1000 样品的尺寸范围为 60-130 nm 的球形颗粒。对 SmFeO3 样品的 Fe L3,2 和 O K 边缘的 X 射线吸收光谱研究揭示了这些材料中 Fe 的同价态。从磁化研究中已经观察到材料表现出铁磁和反铁磁(倾斜自旋结构)子晶格,这导致系统中的强磁各向异性。
