abstract = {Using first-principles calculations, we study the magnetism
of 5d transition-metal atomic junctions including structural
relaxations and spin-orbit coupling. Upon stretching
monoatomic chains of W, Ir, and Pt suspended between two
leads, we find the development of strong magnetism and large
values of the magnetocrystalline anisotropy energy (MAE) of
up to 30 meV per chain atom. We predict that switches of the
easy magnetization axis of the nanocontacts upon elongation
should be observable by ballistic anisotropic
magnetoresistance measurements. Due to the different local
symmetry, the contributions to the MAE of the central chain
atoms and chain atoms in the vicinity of the leads can have
opposite signs which reduces the total MAE. We demonstrate
that this effect occurs independent of the chain length or
geometry of the electrodes.},
