We have investigated the transport and magnetic properties of the atom bridge made from magnetic materials, which is the atom-scale wire constructed between a scanning tunneling microscopy tip and a solid surface, with ab initio calculations. In the case of FeNi alloy bridges, we have found that the atoms in the bridges can be designed to have signiΓΏcantly larger magnetic moment than that in the corresponding alloy bulk. We discuss about the origin of their transport properties in order to design the spin-polarized electron current through the bridges.

The double perovskite, Sr 2 RuTiO 6 has been studied by X-ray powder diffraction, magnetizations and magnetoresistance techniques. Rietveld analysis of the X-ray diffraction shows that the sample crystallizes in tetragonal structure with space group I4/mcm and there is no indication of long range Ru
