Abstract

Nuclear magnetic resonances of 19F in rare earth trifluorides have been measured. The width and shift at any temperature is proportional to the moment of the rare earth ion and follow the susceptibility measurements of Kern and Raccah. A finite and negative shift of −0·3 ± 0.1 per cent has been observed in GdF3 which agrees with −0·46 per cent, expected from the spin polarization calculation of Freeman and Watson. Apart from the usual paramagnetic broadening, resonance widths exhibit diffusion narrowing for the cerium group rare earth fluorides.
