Abstract
NMR study of GdFe2Hx (x = 0, 1.05, 1.7, 2.45, 2.85) hydrides are reported. The values of x chosen at characteristic points of the phase diagram correspond to single phase compounds. Spin echo spectra at zero field and relaxation times T-2 have been measured on powder samples at 4.2 K. The resonances of Gd-155, Gd-157 and H-1 have been identified and the values of the hyperfine fields are obtained. The results are analysed in terms of hydrogen occupation of A2B2 sites and a comparison of hydrogen hyperfine field with dipolar fields at H sites evaluated from lattice sums is made.
