论文摘要
高磁场中的光学探测材料可以提供对现场修饰的电子状态和相位的启发性洞察力，而在高磁场中的光学驱动材料可以诱导新型的非平衡型自旋和电荷载体的多体动力学。尽管存在与标准光谱法兼容的高场磁体，但它们通常是笨重的，并且光学访问有限，这禁止执行最先进的超快和/或非线性光学实验。带有宽带光学元件（RAMBO）的大米高级磁铁是一种具有直接光学访问的独特的30吨脉冲迷你磁铁系统，已实现了先前具有挑战性的实验，该实验使用了飞秒光脉冲，包括时间域Terahertz光谱，在放置在强磁场中的最先进材料中。在这里，我们回顾了第一代兰博设置实现的最新实验进步。在总结了将光谱技术与迷你磁铁磁铁相结合的技术方面之后，我们描述了各种材料的磁光学研究的结果，为固体中四种类型的准粒子的状态和动态提供了新的见解 - 激子，等离子，等离激元，等离子，镁质和声子 - 在高磁场中。
Optically probing materials in high magnetic fields can provide enlightening insight into field-modified electronic states and phases, while optically driving materials in high magnetic fields can induce novel nonequilibrium many-body dynamics of spin and charge carriers. While there are high-field magnets compatible with standard optical spectroscopy methods, they are generally bulky and have limited optical access, which prohibit performing state-of-the-art ultrafast and/or nonlinear optical experiments. The Rice Advanced Magnet with Broadband Optics (RAMBO), a unique 30-T pulsed mini-coil magnet system with direct optical access, has enabled previously challenging experiments using femtosecond optical pulses, including time-domain terahertz spectroscopy, in cutting-edge materials placed in strong magnetic fields. Here, we review recent experimental advances made possible by the first-generation RAMBO setup. After summarizing technological aspects of combining optical spectroscopic techniques with the mini-coil magnet, we describe results of magneto-optical studies of a wide variety of materials, providing new insight into the states and dynamics of four types of quasiparticles in solids - excitons, plasmons, magnons, and phonons - in high magnetic fields.
