摘要

实验研究了 Tb2CoCrO6 氧化物的结构、磁性和磁致性。结果表明，Tb2CoCrO6 氧化物结晶为 B 位无序双超晶系（DP）型正交菱形结构（空间群：Pbnm），磁阶温度约为 2.6 K。89 J/kgK、165.64 J/kg 和 6.76 J/kgK，与最近更新的一些稀土基磁性固体相当，这使得 Tb2CoCrO6 氧化物在实际磁共振应用中具有重要意义。

Magnetic properties and magnetocaloric effect in Tb2CoCrO6 oxide

The structural, magnetic and magnetocaloric properties in Tb₂CoCrO₆ oxide have been experimentally investigated. The results indicate that the Tb₂CoCrO₆ oxide crystallizes in a B-site dis-ordered double-perovskite (DP)-type orthorhombic structure (space group: Pbnm) and with magnetic order temperature of around 2.6 K. The determined magnetocaloric parameters in Tb₂CoCrO₆ oxide including the maximum magnetic entropy change, relative cooling power, and temperature-averaged entropy changes (5 K-lift) reach 6.89 J/kgK, 165.64 J/kg, and 6.76 J/kgK under magnetic field variation of 0–5 T, respectively, which are comparable with some recently updated rare earth-based magnetic solids, making the Tb₂CoCrO₆ oxide interesting for practical MR applications.

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.
