    "abstract": "A quantum pump device involving magnetic barriers produced by the deposition\nof ferro magnetic stripes on hetero-structure\u0027s is investigated. The device for\ndc- transport does not provide spin-polarized currents, but in the adiabatic\nregime, when one modulates two independent parameters of this device, spin-up\nand spin-down electrons are driven in opposite directions, with the net result\nbeing that a finite net spin current is transported with negligible charge\ncurrent. We also analyze our proposed device for inelastic-scattering and\nspin-orbit scattering. Strong spin-orbit scattering and more so inelastic\nscattering have a somewhat detrimental effect on spin/charge ratio especially\nin the strong pumping regime. Further we show our pump to be almost noiseless,\nimplying an optimal quantum spin pump.",
