The oxidation behaviour of the Nd2Fe14B phase is followed by nuclear magnetic resonance of Nd16Fe76B8 powders oxidized in ambient air at temperatures between 200 and 650 °C. It is shown that upon oxidation in the 200-400 °C temperature range, the d

89Y (spin I=1/2) NMR studies of DyFe2/YFe2 multilayer films at 4.2 K are reported and discussed. Results are presented for a 1000 A thick film of YFe2, and a 24,000 A thick superlattice film [300 A DyFe2/300 A YFe2]×40. For comparative purposes, mea
