WebSep 26, 2024 · The crystal-field splitting within the single-ion ground-state manifold is investigated by inelastic neutron scattering on powder samples. A strong temperature dependence of the quasidoublet ground state is observed and revised parameters of the crystal-field Hamiltonian are given. The results of bulk magnetic susceptibility and … WebDec 7, 2016 · Spatial symmetry is readily apparent in a crystal-field Hamiltonian, that is, one can just examine the potential and see the spatial symmetries. I'm a bit confused about how to check if the system has time-reversal symmetry, particularly in the case of integer J (even number of electrons).
WebOct 15, 2024 · The crystal field splitting energy levels of Nd3+ in NdBa 2 Cu 3 O 7 can be obtained from diagonalization of the effective Hamiltonian. The calculated energy values can agree very well with the experimental values given by previous papers. WebThe terms in the Hamiltonian that represent the non-spherical part of the interaction with the crystal are modeled using the so-called crystal-field Hamiltonian. It is important to recognize that this Hamiltonian is not restricted to electrostatic effects, which form a minor part of the total crystal-field effect (Ng and Newman, 1987).
