10. Exploring finite-temperature electronic transport in CoSi alloys with transition metals (Cr, Mn, Fe, and Ni) using the KKR-CPA method.

Abstract

The finite-temperature electronic transport properties of the CoSi compound and its alloys with 3d transition metals including Fe, Cr, Mn, and Ni are elucidated by using the Korringa–Kohn–Rostoker Green's function method combined with the coherent potential approximation. On the basis of the linear response theory, the electrical resistivity of the CoSi compound observed in the experiments could be quantitatively reproduced by taking into account both local phonon displacements and antisite disorder effects. Our calculations reveal the formation of Co–Si disorders with a very small concentration and their dominant effect on resistivity in a low-temperature range. Moreover, alloying transition metals with CoSi also led to significant changes in the states of conduction electrons, which is interesting as a typical example of a rigid band scheme. Notably, we found that alloying with Ni could reduce the system's resistivity by more than 25%, suggesting its potential for enhancing the power factor of the CoSi compound for thermoelectric applications.

11. Pressure-dependent multiplet-excitation energies of α-Al2O3:Cr3+by the first-principles method

Author

Saito, Harutaka, Suzuki, Katsuhiro, Sato, Kazunori, and Kotani, Takao

Abstract

We apply a method [Phys. Rev. B108, 035141 (2023)], which can treat the multiplet excitations in the first-principles method, to a typical pressure indicator α-Al2O3:Cr3+. After optimizing the crystal structure under hydrostatic pressure from 0.0 to 35.0 GPa in the usual first-prinicple calculations, we obtain the multiplet energies in the method. That is, we conduct the exact diagonalization of the crystal-field model Hamiltonian which is directly determined based on the result of the quasiparticle self-consistent GW method. Our method has no parameters by hand. The calculated pressure dependences of the excitation energies agree well with those of experiments.
