自旋轨道物理在相关系统中产生新相:铱酸盐和相关材料

Spin-Orbit Physics Giving Rise to Novel Phases in Correlated Systems: Iridates and Related Materials

Jeffrey G. Rau, Eric Kin-Ho Lee, Hae-Young Kee

摘要:

近年来,关联物质中的自旋轨道耦合效应(SOC)已成为凝聚态物理中最活跃的研究课题之一,因为关联和SOC一起可以导致新相的发现。在候选材料中,铱氧化物(铱酸盐)一直是发现这种新现象的绝佳场所。在这篇综述中,我们讨论了最近的进展,在铱酸盐和相关材料,侧重于基本概念,相关的微观哈密顿量,和不寻常的性能的铱酸盐在钙钛矿和蜂窝结构。SOC和相关物理超越虹膜的观点也进行了讨论。

英文摘要:

Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one of the most actively studied subjects in condensed matter physics, as correlations and SOC together can lead to the discovery of new phases. Among candidate materials, iridium oxides (iridates) have been an excellent playground to uncover such novel phenomena. In this review, we discuss recent progress in iridates and related materials, focusing on the basic concepts, relevant microscopic Hamiltonians, and unusual properties of iridates in perovskite- and honeycomb-based structures. Perspectives on SOC and correlation physics beyond iridates are also discussed.
