Abstract
Proton magnetic resonance (PMR) in a ferromagneticΒ-uranium hydride at 77 K has been searched unsuccessfully between 4 and 420 MHz. The present communication reports this experiment and its objectives, and justifies the swept frequency range on the basis of PMR data obtained in the paramagnetic phase and of a new analysis of the Flotow and Osborne low temperature specific heat data. It is shown that experimental conditions were at least as favourable as those for observing PMR in the paramagnetic phase. Specific heat measurements below 1 K, using the Dempesey et al. method, seem necessary before pushing experimental efforts further.
