Abstract

NMR results in RE-Fe2 internmtallic compounds at low temperatures are reported. Using a spin-echo spectrometer in the U.H.F. range, hyperfine field parameters have been measured on 167Er, 163Dy, 169 Tn and 159Tb at 1.4K. These cctnpounds have high Curie temperatures and the magnetic moment of the rare-earth, gJμB<Jz> is nearly saturated. The value of the iron moment is also known from Mossbauer measurements and accurate data for the hyperfine field at the rare-earth site obtained from NM enables us to extract the internal field due to conduction electrons.
