Abstract

Magnetic properties of crystalline solids are fundamental to a wide range of applications, capturing the attention of a vast scientific community. Thus, engineering magnetic order in materials such as ferromagnetism and antiferromagnetism holds great scientific and technological interest. Defects such as vacancies, interstitials, and dopants induce local perturbations within the crystal lattice. These perturbations locally disturb the entire symmetry of crystals, resulting in symmetry breaking. Oxides, in particular, exhibit intriguing properties when subjected to defects, which can lead to significant modifications in their structural, electronic, and magnetic properties. Such defects in non-magnetic oxides can induce magnetic symmetry breaking, leading to the formation of emergent magnetic domains and orderings. In this review, we focus on the recent progress in magnetic breaking symmetries in materials via defect engineering and present our perspectives on how these may lead to new understanding and applications.

氧化材料中缺陷引起的磁对称性破缺

晶体固体的磁性是广泛应用的基础，引起了广大科学界的关注。因此，铁磁性和反铁磁性等材料的工程磁序具有重大的科学和技术意义。空位、间隙和掺杂等缺陷会引起晶格内部的局部扰动。这些扰动局部扰乱了晶体的整个对称性，导致对称性破坏。特别是氧化物，当受到缺陷时，会表现出有趣的特性，这可能导致它们的结构、电子和磁性能发生重大变化。这种缺陷在非磁性氧化物中会引起磁对称性破缺，导致紧急磁畴和有序的形成。在这篇综述中，我们重点介绍了通过缺陷工程研究材料中磁破对称性的最新进展，并就这些进展如何导致新的理解和应用提出了我们的观点。
