β¦ Synopsis
Impressive progress has been made during past decades in many research fields which apply NMR, pushing the proton resonance frequency from 30 MHz (0.7 T) to about 800 MHz (19 T). In this overview we analyze different technologies for generation of the required fields and their potential for future developments toward even higher resonance frequencies of up to 2 GHz.

## Abstract Strong, extensive magnetic fringe fields are a significant problem with magnetic resonance imaging magnets. This is particularly acute with 4βT, wholeβbody research magnets. To date this problem has been addressed by restricting an extensive zone around the unshielded magnet or by placi
A platinum nuclear magnetic resonance (NMR) thermometer has been developed for use in high magnetic fields (10 T) at low dilution refrigerator temperatures (10 mK). The design consists of fine platinum wires cooled by a heat exchanger of pressed silver powder. Nuclear magnetic heat capacity, thermal
