Abstract

The simple lattice and magnetic structure, the high Néel temperature, the narrow antiferromagnetic resonance line of FeBO₃, and the narrow electron paramagnetic resonance line of its isostructural diamagnetic analogs MBO₃:Fe³⁺ (M = Ga, In, Sc, Lu) make iron borate unique for investigations and applications. Iron borate is a model crystal for numerous experimental and theoretical studies, including spin crossovers and metallization at megabar pressures and many-electron effects in optics and X-ray spectroscopy. The recent works dealing with the investigation of the properties of FeBO₃ are reviewed.

弱反铁硼酸铁FeBO 3。磁性的经典对象和最新技术

摘要

其简单的晶格和磁性结构，较高的Néel温度，FeBO _3的反铁磁共振线窄以及其等结构抗磁性类似物MBO ₃：Fe ³⁺的窄电子顺磁共振线（M = Ga，In，Sc，Lu）使硼酸铁在研究和应用方面独树一帜。硼酸铁是用于许多实验和理论研究的模型晶体，包括自旋交叉和兆巴压力下的金属化以及光学和X射线光谱学中的多电子效应。综述了有关FeBO ₃性质研究的最新工作。
