论文摘要
我们提出了一种在超低场核磁共振（NMR）实验中开发的系统，以使液态样品预先磁性。几毫升的液体样品暴露于约70毫米的磁场，该磁场突然关闭，因此要留下一个横向微动物场，核开始核开始进化。瞬态和中间场水平的准确表征可以实现基于光学磁力计的检测系统的可靠操作。
We present a system developed to premagnetize liquid samples in an ultra-low-field Nuclear Magnetic Resonance (NMR) experiment. Liquid samples of a few milliliter are exposed to a magnetic field of about 70~mT, which is abruptely switched off, so to leave a transverse microtesla field where nuclei start precessing. An accurate characterization of the transients and intermediate field level enables a reliable operation of the detection system, which is based on an optical magnetometer.
