We have measured the temperature and field dependence of the magnetization of several rapidly solidified Nd0.14(Fe1−xAlx)0.80B0.06 alloys in the 290–500 K temperature range at fields from 0 to 0.9 T. At room temperature the materials are ferromag

We report calculations of 5s electron excitation energies for the rare-earth metals. Aside from the lack of a direct estimate of correlation effects, the method is quite similar to that we have used in calculating 4f-level positions which are in exce

Free-atom-to-metal shifts of several lanthanide core electron binding energies were calculated. The shifts were obtained directly from relativistic Hartree-Fock calculations of the individual atomic and solid state binding energies. Results for the 2

A procedure has been expressly developed for calculating excitation energies of localized states in the rare earth metals. Relativistic Hartree-Fock computations for appropriate atomic configurations are performed initially, and crystal potentials ar

We report Rietveld analyses of neutron powder diffraction data on Ce 2 Fe 14 B and Lu 2 Fe 14 B, two phases which form the tetragonal Nd 2 Fe 14 B crystal structure. The data for both compounds can be accommodated well with the assumption that only t
