We have performed normal-to-plane magneto transport measurements in single crystalline 100 W and Mo nanostructures down to 1.5 K. Fabricated nanostructures possess large mean free path due to their bulk crystalline perfection and low surface roughness. Under these conditions electrons scatter only on the boundaries of nanostructures and may travel long distance without scattering. We found that in this regime the normal-to-plane magnetoresistance of planar metallic nanostructures exhibit specific for ballistic transport attributes such as transverse magnetic focusing suppression of Hall resistance quenching Hall effect and negative bend resistance at moderate magnetic fields.
