A. Mirmelstein et al., NEUTRON SPECTROSCOPIC STUDY OF CRYSTALLINE ELECTRIC-FIELD IN INFINITE-LAYER SR1-XNDXCUO2, Physica. C, Superconductivity, 282, 1997, pp. 1335-1336
Inelastic neutron scattering has been employed to search for the cryst
alline-electric-field (CEF) transitions in the infinite-layer (LL) Sr1
-xNdxCuO2 compounds produced by high-pressure technique. For the first
time we have been able to observe the complete energy spectrum of the
ground state J-multiplet of Nd3+ in the IL phase and to determine the
CEF parameters. Dependence of the CEF splitting on Nd doping is discu
ssed.
