摘要
我们分析了核自旋对磁力共振显微镜悬臂运动的反作用影响。我们计算了核自旋对悬臂阻尼和频移的贡献。我们表明，在拉比频率下，悬臂与自旋系统之间的能量交换会冷却或加热悬臂，具体取决于高频失谐的符号。我们还表明，自旋噪声会导致悬臂运动的显著阻尼。

备注
15 pqges, 11 figures. The last part of Section IV.A and Section IV B were rewritten. We added three new graphs: Figs. 5, 7, 9 and all graphs in this subsection were recalculated for T=600 mK as in the experiment. Several new references were added
