AbstractUsing ab-initio spin-polarized layer Korringa-Kohn-Rostoker (LKKR) band structure calculations, we investigated the possibility of having a stable ferromagnetic ground state in 4d transition metal (TM)–Ag(001) sandwiches (TM = Tc, Ru, Rh, and Pd). In contrast to recent calculations performed on systems with TM overlayers on Ag (001), we find that the TM sandwich configuration gives a paramagnetic ground state. While excellent agreement in general is obtained for the layer-projected densities of states (LDOS), the sandwich configuration lowers the densities of states at the Fermi energy (EF) in the case of Rh and Ru by a small amount which seemingly prevents the marginal ferromagnetic instability predicted by Eriksson et. al. (Phys. Rev. Lett. 66, 1350 (1991)) from occurring.

ABSTRACTTotal energies of binary and ternary -metral trialminides in the L12DO22 Do23Structures and binary Transition- metal disilicides in the C1lb, C40, C54, and C49 structures have been obtained by ab initio band-structure calculations. In aluminides the tetragonal Do22 and Do23 structures are stabilized relative to cubic L12P and in silicides the hexagonal C40 structure is stabilized relative to orthorhombic C54 and tetragonal C11b relative to C40, as the transition-metal d-electron count increases. The observed easier stabilization of L12 in Ti(AI,Fe) 3 relative to Nb(AI,Fe)is justified by the calculations. Location of the Fermi level in a quasigap in the density of states distribution rationalizes the observed structural stabilities in aluminides but not in silicides.

Phase diagrams and phase stabilities have in the past been dealt with using different approaches. In the Calphad method one seeks a description of the Gibbs energy function G(T) which is accurate enough to be used in calculations of phase diagrams for complex alloys. Ab initio electron band structure calculations, on the other hand, have been used to predict the cohesive properties of solids but such calculations are usually restricted to 0 K. We have combined these methods to get a better understanding of the phase stabilities. In particular we have critically analysed available thermodynamic information and used that together with band structure calculations to systematically discuss trends in the cohesive energy at 0 K and in the vibrational entropy. We have considered transition-metal carbides and nitrides, both in the NaCl and in more complex structures, and also transition-metal diborides.
