Current-driven magnetic rearrangements in spin-polarized point contacts
Maria Stamenova, Stefano Sanvito, Tchavdar N. Todorov
A new method for investigating the dynamics of atomic magnetic moments in current-carrying magnetic point contacts under bias is presented. This combines the non-equilibrium Green'…
HfO: a new direction for intrinsic defect driven ferromagnetism
Chaitanya Das Pemmaraju, S. Sanvito
In view of the recent experimental reports of unexpected ferromagnetism in HfO thin films, we carried out first principles investigations looking for magnetic order possibly…
Density functional calculations for III-V diluted ferromagnetic semiconductors: A Review
S. Sanvito, G. Theurich, N. A. Hill
In this paper we review the latest achievements of density functional theory in understanding the physics of diluted magnetic semiconductors. We focus on transition metal doped III…
Material-specific spin filtering in ferromagnet/superconductor ballistic nanojunctions
F. Taddei, S. Sanvito, C. J. Lambert
We study spin-dependent electronic transport across ferromagnet/superconductor ballistic junctions modeled using tight-binding Hamiltonians with s, p and d orbitals and material-sp…
Suppression of Giant Magnetoresistance by a superconducting contact
F. Taddei, S. Sanvito, J. H. Jefferson +1
We predict that current perpendicular to the plane (CPP) giant magnetoresistance (GMR) in a phase-coherent magnetic multilayer is suppressed when one of the contacts is superconduc…
Infinite magnetoresistance of magnetic multilayers
R. Seviour, S. Sanvito, C. J. Lambert +1
We examine transport properties of a magnetic superlattice with current perpendicular to the planes. In the limit that the phase-breaking and spin flip scattering lengths are great…
