We have investigated infinitely long, monostrand Pt nanowires theoretically,
and found that they exhibit Hund's rule magnetism. We find a spin moment of 0.6
Bohr magnetons per atom, at the equilibrium bond length. Its magnetic moment
increases with stretching. The origin of the wire magnetism is analyzed and its
effect on the conductance through the wire is discussed.
