摘要： 拉曼散射是一种同时确定晶格、自旋和电荷自由度动力学的优秀方法。 此外，拉曼散射中的偏振选择规则使动量分辨的准粒子动力学成为可能。 在本综述中，我们强调了拉曼散射在探测各种磁性材料中的磁性准粒子或激发方面的潜力。 我们展示了温度依赖的拉曼散射数据如何证实长程有序磁体中的磁振子和Kitaev自旋液体候选材料中的分数化激发的存在。 为了使本综述易于新手理解，我们提供了关于磁振子和分数化激发的背景信息，并解释了它们如何在拉曼散射过程中变得可见。 我们还展示了如何从数据中估算磁交换相互作用。 对于这两种类型的磁性材料，我们讨论了自旋-声子耦合对声子模式线形的影响。 在材料方面，我们展示了反铁磁Sr2IrO4和La2CuO4的磁性拉曼散射数据，铁磁CrI3单层，以及Kitaev自旋液体候选材料{\alpha }-RuCl3和\b{eta}-Li2IrO3。 总体而言，我们的综述展示了拉曼散射技术在探测磁性量子材料中准粒子的多功能性。 本综述旨在向年轻实验研究人员介绍拉曼散射的潜力，从而激励他们在研究中使用这一技术。 显示英文摘要

摘要： Raman scattering is an excellent method for simultaneously determining the dynamics of lattice, spin, and charge degrees of freedom. Furthermore, polarization selection rules in Raman scattering enable momentum-resolved quasiparticle dynamics. In this review, we highlight the potential of Raman scattering in probing magnetic quasiparticles or excitations in various magnetic materials. We demonstrate how temperature-dependent Raman scattering data can confirm the existence of magnons in long-range ordered magnets and fractionalized excitations in Kitaev spin liquid candidates. To make this review easily understandable to novices, we provide background information on magnons and fractionalized excitations, and explain how they become visible in the Raman scattering process. We also show how to estimate magnetic exchange interactions from the data. For both types of magnetic materials, we discuss the impact of spin-phonon coupling on the lineshape of the phonon modes. In terms of materials, we present magnetic Raman scattering data of antiferromagnetic Sr2IrO4 and La2CuO4, ferromagnetic CrI3 monolayers, and Kitaev spin liquid candidates {\alpha}-RuCl3 and \b{eta}-Li2IrO3. Overall, our review demonstrates the versatility of the Raman scattering technique in probing quasiparticles in magnetic quantum materials. The review aims to inform young experimental researchers about the potential of Raman scattering, thereby motivating them to use this technique in their research.
