Abstract:
The influence of microwave irradiation on the recovery of nanocrystalline PrF3 powders has been experimentally analyzed by nuclear magnetic resonance (NMR) at T = 1.5 K. It is established that the relaxation times of 141Pr and 19F nuclei rise significantly with an increase in the hydrothermal-treatment time, whereas the 141Pr NMR spectra narrow, which indicates a decrease in the number of defects in the lattices of nanosamples. © 2014 Pleiades Publishing, Ltd.
