Crystal electric field and dynamics of spin fluctuations in CeAl
A. A. Vasil’kevich, P. G. Ivanitskii, V. I. Slisenko, V. T. Krotenko, A. N. Maistrenko, V. Ya. MarkivCrystal electric field (CEF) effects in CeAl are studied with the help of inelastic neutron scattering. The parameters of CEF Hamiltonian with an orthorhombic symmetry point group of a rare-earth ion are determined from the neutron spectra. The energy level diagram of the fundamental multiplet 2F5/2 of a Ce3+ ion in the CEF of CeAl is obtained. Temperature dependences of the Schottky specific heat and magnetic susceptibility are calculated. The theoretical magnetic susceptibility is compared with the experimental value.
