Two nanosized PrF 3 samples were synthesized using two different procedures. The X-ray and HRTEM experiments showed high crystallinity of synthesized samples. Comparison of enhanced 141Pr NMR spectra of microsized (45 μm) and nanosized PrF 3 powder is presented. Experimental data on spin kinetics of 3He in contact with PrF 3 nanoparticles at T=1.5 K are reported. © 2010 Springer Science+Business Media, LLC.
