论文摘要
Hartmann-Hahn技术通过将所研究的旋转与外部驱动的另一个自旋物种耦合，可以增强磁共振成像和光谱。在这里，我们从理论上研究了耦合旋转的动力学，并发现在某个驱动参数的区域中，系统变得不稳定。讨论了使该区域成为实验可访问的所需条件。
The Hartmann-Hahn technique allows sensitivity enhancement of magnetic resonance imaging and spectroscopy by coupling the spins under study to another spin species that is externally driven. Here we theoretically study the coupled spins' dynamics, and find that for a certain region of driving parameters the system becomes unstable. The required conditions for making this region of instability becoming experimentally accessible are discussed.
