摘要

最近的研究突显了双包晶石的显著特点，即通过掺入元素周期表中的各种元素，使其具有多种特性。其中，六方双包晶石因其潜在的量子特性而日益受到关注。我们的研究侧重于 6H 六方双包晶石 BaCo[CoRu]O，揭示了 Co 离子和 Ru 离子的混合价态以及显著的电荷转移现象。通过分析金属离子的怀科夫位置以及考虑结构和磁性能，我们揭示了交换偏置机制。我们的研究强调了六方包晶结构在适当离子组成下产生巨大交换偏压的重要性，突出了合理材料设计的作用。

Exploring the origin of exchange bias and spin glass behavior in 6H hexagonal perovskite structure: Structural and magnetic analysis

Recent research has highlighted the prominence of double perovskites for their diverse properties by incorporating elements across the periodic table. Among them, the hexagonal double perovskite is a subject of growing interest for its potential quantum properties. Our study focuses on the 6H hexagonal double perovskite BaCo[CoRu]O, revealing mixed valence states of Co and Ru ions and notable charge transfer phenomena. By analyzing metal ion Wyckoff positions and considering structural and magnetic properties, we uncover insights into exchange bias mechanisms. Our study underscores the significance of hexagonal perovskite structures in yielding giant exchange bias with appropriate ionic compositions, highlighting the role of rational material design.
