Description

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 T2 have been measured on powder samples at 4.2-bar K. The resonances of Gd155, Gd157 and H1 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
