Platinum monatomic nanowires were predicted to spontaneously develop magnetism, involving a sizable orbital moment via spin orbit coupling, and a colossal magnetic anisotropy. We present here a fully-relativistic (spin-orbit coupling included) pseudo-potential density functional calculation of electronic and magnetic properties, and of Landauer ballistic conductance of Pt model nanocontacts consisting of short nanowire segments suspended between Pt leads or tips, reprented by bulk planes.

Ballistic Anisotropic Magnetoresistance of Single-Atom Contacts.
This work shows that engineering the AMR at the single atom level is feasible and large changes of the magnetoresistance occur from the tunneling to the ballistic regime due to the competition of localized and delocalized d-orbitals, which are differently affected by spin-orbit coupling.
Finite temperature orbital and spin magnetism of small Fe linear chains.
The temperature dependence of the orbital cluster moment follows a general trend similar to that of the spin one and shows clear anisotropy effects at low and intermediate temperatures, before total thermal disorder appears.

Noncollinear magnetic order induced by Dzyaloshinskii-Moriya interaction in oxygen-assisted Pt nanojunctions.
First principle calculations of the magnetic order and electronic transport by explicitly including fully relativistic effects show that the spin alignment is a cycloidal spiral feature attributed to the Dzyaloshinskii-Moriya interaction, which indicates that the observed magnetism in experiments is of noncollinear nature.

Colossal magnetic anisotropy of monatomic free and deposited platinum nanowires.
This work discusses here, on the basis of density functional calculations, the novel and unconventional feature of colossal magnetic anisotropy--the strict impossibility of magnetization to rotate from the parallel to the orthogonal direction--which, owing to a quantum mechanical selection rule, the recently predicted Pt nanowire magnetism should exhibit.

Evidence for spontaneous spin-polarized transport in magnetic nanowires.
It is shown that ferromagnetic suspended atom chains spontaneously display an electron transport of half a conductance quantum, as expected for a fully polarized conduction channel, suggesting that the nanowire low dimensionality reinforces or induces magnetic behavior, lifting off spin degeneracy even at room temperature and zero external magnetic field.
