title: Spintronics (Communication arising): Spin accumulation in mesoscopic systems.
abstract: Johnson suggests that our results are not due to spin transport but rather are caused by spurious effects, in particular the anisotropic magneto resistance of the ferromagnetic contacts. However, our experiment was designed explicitly to eliminate any magneto-resistance effects that might arise from the ferromagnetic contacts.
