We have performed first-principles calculations of the magnetic properties of the overdoped (x=0.25) LSCO and Fe-LSCO systems. Originally, without impurities of iron, La1.75Sr0.25CuO4 is nonmagnetic. Replacing one of Cu atoms in a unit cell with an F

Hyperfine parameters of iron nuclei such as isomer shift, quadrupole splitting, and asymmetry parameter are calculated for β-FeSi 2 with and without vacancies, using density functional theory. They are applied, in combination with parameters of α-F
