本文介绍了一种新的方法，即在压砧室的高压区使用射频微线圈进行核磁共振（NMR）实验。首次获得了70kbar高灵敏度的Al NMR数据。在70千巴的Al奈特位移的预期减少，以及在Al核的局部电荷对称性的意外变化。后者不是通过高压下的化学结构分析预测的。
A novel approach that uses radio-frequency microcoils in the high-pressure region of anvil cells with Nuclear Magnetic Resonance (NMR) experiments is described. High-sensitivity Al NMR data at 70 kbar for Al metal are presented for the first time. An expected decrease in the Al Knight shift at 70 kbar is observed, as well as an unexpected change in the local charge symmetry at the Al nucleus. The latter is not predicted by chemical structure analysis under high pressure.
