Following a tradition of very low temperature studies, we employ a dilution-refrigerator system to perform NMR measurements down to 70 mK, where unwanted thermal agitation is minimized. Unlike other conventional configurations, our design allows us to thermally decouple the sample from the NMR coil and, hence, cover a wider temperature range, while maintaining the top-load capability.
