Abstract:
The resonance magnetic coupling between the nuclei of liquid 3He and the 141Pr nuclei of a fine-dispersed powder of PrF3 Van Vleck paramagnet with the grain size below 45 μm has been discovered at a temperature of 1.5 K with the use of a pulsed NMR technique. The magnetic specific heat of the corresponding spin systems is estimated theoretically.
