Query: Ballistic anisotropic magnetoresistance   Electronic transport in ferromagnetic ballistic conductors is predicted to
exhibit ballistic anisotropic magnetoresistance (BAMR) - a change in the
ballistic conductance with the direction of magnetization. This phenomenon
originates from the effect of the spin-orbit interaction on the electronic band
structure which leads to a change in the number of bands crossing the Fermi
energy when the magnetization direction changes. We illustrate the significance
of this phenomenon by performing ab-initio calculations of the ballistic
conductance in ferromagnetic Ni and Fe nanowires which display a sizable BAMR
when the magnetization changes direction from parallel to perpendicular to the
wire axis.
