Abstract

For the first time large samples of the nominal composition Sr_1-xNd_xCuO₂ (x=0.07, 0.15) 10 g in mass each have been prepared using a high-pressure technique. Neutron-diffraction and X-ray measurements have shown that the main phase in the samples obtained is of the infinite-layer structure which has been refined in the tetragonal P4/mmm space group. Both samples are not superconducting. Inelastic neutron scattering has been employed to search for crystalline-electric-field transitions in these compounds. The observed low-energy spectra exhibit one inelastic line of magnetic origin at 18 meV, comparable in energy with a crystalline-electric-field excitation in the high-T_c superconductor NdBa₂Cu₃O_x.
