Abstract
A nuclear magnetic resonance spectrometer is described, which was constructed to investigate metals and especially metal single crystals at temperatures between 1.5 and 300°K and at fields up to 5 tesla units (T; 1 tesla unit = 10 kG). A superconducting NbTi magnet system was built with adjustable compensation coils. Data acquisition takes place using the Hewlett-Packard timer-counter, model 5326 B, in connection with remote programming allowing subsequent exact data processing with a computer. An example is given for a vanadium single crystal, the resonance frequency of which has been measured in the range from 110 to 230°K.
