Opis:: $UNiAs_2$ band structure has been calculated based on two full-potential methods: full potential linearized augmented plane wave implemented in WIEN2k code and full-potential local-orbital minimum-basis in FPLO code. Starting from the local (spin) density approximation (L(S)DA) we verified either the orbital polarization correction or the LSDA+U approach with the Coulomb repulsion energies U of 0-4 eV for the uranium 5f electrons. Calculated magnetic moments confirm antiferromagnetic ground state and collinear magnetic sequence. The best agreement with experimental results has been achieved by applying orbital polarization corrections, the magnetic moment on uranium amounts to 1.76 $μ_{B}$ per U atom.

Opis:: $U_5Ge_4$ crystallizes in a hexagonal $Ti_5Ga_4$ type structure with two inequivalent crystallographic sites occupied by uranium atoms. The band structure calculations were performed by the full-potential local-orbital minimum basis band structure code. The calculations showed that on both types of uranium atoms small magnetic moments are formed and their values are equal to 0.08 and 0.15 $μ_{B}$/atom, respectively.

Opis:: $Ce_5CuPb_3$ band structure has been calculated based on two ab initio methods: full potential-linearized augmented plane wave implemented in WIEN2k code and full-potential local-orbital minimum-basis in FPLO code. The calculations were performed with and without spin polarization. Starting from the generalized gradient approximation we additionally tested either an orbital polarization correction and the GGA+U approach with the Coulomb repulsion energies U varied from 0 to 6.7 eV within the Ce 4f electron shell. The calculations confirmed possible antiparallel alignment of the magnetic moments of the cerium atoms in the low temperature phase.
