Nanomagnetomechanics and lattice-resolved spin dynamics

由于纳米科学和纳米技术之间惊人的反馈循环，这是历史上研究新材料的物理和应用的最激动人心的时刻。对信息技术的终极物理极限的追求为凝聚态物理的基础研究提供了一个有趣的焦点。传统的磁性信息存储已经发展到“纳米”状态，而自旋电子学和纳米磁逻辑等新技术的潜力是巨大的。这些系统的运行速度有多快之类的问题，可以通过实验来回答，方法是剧烈地干扰它们（比如快），然后观察它们的反应，类似于敲击音叉并听它响。随着系统规模的缩小，这变得越来越具有挑战性。我们的工作得益于纳米制造、激光和显微镜技术的进步。这些技术使我们能够研究单个的纳米物体。

This is the most exciting time in history to be working on the physics and applications of new materials, thanks to the phenomenal feedback loop between nanoscience and nanotechnology. The quest towards ultimate physical limits of information technology provides an interesting focus for basic investigations in condensed matter physics. Conventional magnetic information storage has already evolved far into the "nano" regime, and the potential for new technologies such as spin electronics and nanomagnetic logic is enormous. Questions such as how quickly these systems can operate can be answered experimentally by perturbing them sharply (as in fast), and observing the response, akin to hitting a tuning fork and listening to it ring. This becomes progressively more challenging as the systems decrease in size. Our work is enabled by advances in nanofabrication, lasers, and microscopy. Together these allow us to study individual nano-objects.
