Figure 1: Stray-field apparatus for imaging nuclear magnetism.
From: Optically rewritable patterns of nuclear magnetization in gallium arsenide
The strong gradient in the stray field of a superconducting magnet provides the means for NMR imaging in one-dimension. Circularly polarized illumination is directed to the sample through an optical window on the sapphire sample support. Inset: the NMR pulse sequence including saturation, illumination and detection.
