Abstract

Inelastic neutron scattering has been employed to search for the transitions between the lowest lying levels of the J-multiplet of the Ho³⁺ ions in Ho_1-xCa_xBa₂Cu₃O_y (x = 0-0.3; y = 6.3-7) split by crystalline electric field (CEF). The observed energy spectra all exhibit a complex fine structure, which reflects the behavior of the local hole density near the doping center. We have found that the obtained results can be explained in terms of the model of the CEF generated by the ordered planar charge structure.
