Electronic structure, magnetism, and spin fluctuations in the superconducting weak ferromagnetY4Co3

Half-metallic alloys: electronic structure, magnetism and spin polarization.

Using the state-of-the-art screened Korringa-Kohn-Rostoker Green function method we study the electronic and magnetic properties of NiMnSb and similar Heusler alloys. We show that all these compounds are half-metals, e.g. the minority-spin band is semiconducting and the Fermi level falls within this gap resulting in 100% spin polarization at the Fermi level. The total spin moment M(t) shows the...

Orbital magnetism and spin-orbit effects in the electronic structure of BaIrO3.

The electronic structure and magnetism of Ir 5d5 states in nonmetallic, weakly ferromagnetic BaIrO3 are probed with x-ray absorption techniques. Contrary to expectation, the Ir 5d orbital moment is found to be ~1.5 times larger than the spin moment. This unusual, atomiclike nature of the 5d moment is driven by a strong spin-orbit interaction in heavy Ir ions, as confirmed by the nonstatistical ...

Electronic structure and magnetism of Fe1ÀxPdx alloys

An ab initio linearized augmented plane-wave method has been employed to calculate the electronic and magnetic structures of both face-centered-cubic and body-centered-cubic Fe12xPdx alloys with x50.25, 0.50, and 0.75, respectively. Decreasing the Pd content in Fe12xPdx alloy from x51, the magnetic ordering of fcc Fe12xPdx changes from paramagnetism to ferromagnetism, ferrimagnetism, and finall...

Charge and Spin Transport in Superconducting Weak Links

The coherent mixing of the current states in the superconducting weak link subject to a Josephson phase difference φ and subject to an external transport current in the banks is one of the aims of this work. At φ = π the nonlocal mixing of current states produces two vortices close to the point-contact between superconducting bulks. The effect of point-contact reflection in an impenetrable inte...
