利用固体空气中的氧顺磁性测量悬臂梁末端的温度

Temperature measurement at the end of a cantilever using oxygen paramagnetism in solid air

Kent R. Thurber, Lee E. Harrell, Doran D. Smith

摘要:

我们演示了温度测量的样品连接到悬臂的末端,使用悬臂的固体空气“污染”的样品表面的磁性。在我们的磁共振力显微镜(MRFM)等实验中,样品安装在具有小热导率的薄悬臂梁的末端。因此,样品可以处于与仪器主体显著不同的温度。使用悬臂梁磁力测量法在固体空气中的氧顺磁性提供了样品的温度,而无需对我们的MRFM(磁共振力显微镜)设备进行任何修改。

英文摘要:

We demonstrate temperature measurement of a sample attached to the end of a cantilever using cantilever magnetometry of solid air ``contamination'' of the sample surface. In experiments like our Magnetic Resonance Force Microscopy (MRFM), the sample is mounted at the end of a thin cantilever with small thermal conductance. Thus, the sample can be at a significantly different temperature than the bulk of the instrument. Using cantilever magnetometry of the oxygen paramagnetism in solid air provides the temperature of the sample, without any modifications to our MRFM (Magnetic Resonance Force Microscopy) apparatus.
