摘要

SmFeO3通过调整其磁性和极性顺序参数，将成为未来设备应用的潜在材料。本文采用系统的温度随磁化强度变化研究了SmFeO3陶瓷样品在低温至350 K不同磁场下的磁序。在场冷却（FC）和零场冷却（ZFC）模式中观察到一个有趣的现象。在FC和ZFC模式下的磁化温度变化表现为磁化强度的反转，在10 kOe磁场下达到3.8 K的交叉温度。在钐铁氧体中，铁和钐亚晶格的各种磁性贡献表现出磁性和极性顺序。

Temperature dependent variation of magnetic properties of SmFeO3 ceramic

SmFeO₃ will be a potential material for futuristic device applications by tailoring its magnetic and polar order parameters. In this report, the magnetic order of the SmFeO₃ ceramic sample is probed by systematic temperature dependent variation of magnetization under different magnetic fields from low temperature to 350 K. An interesting phenomenon is observed in field cooled (FC), and zero fields cooled (ZFC) modes. Temperature variation of magnetization in FC and ZFC mode shows reversal of magnetization, and a crossover temperature is reached at 3.8 K under magnetic field 10 kOe. The onset of various magnetic contributions from both Fe and Sm sublattices exhibits magnetic and polar orders in samarium ferrites.

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
