Abstract
We formulate a theory of spin dependent transport in an electronic circuit involving ferromagnetic elements with noncollinear magnetization which is b ased on the conservation of spin and charge current. The theory considerabl y simplifies the calculation of the transport properties of complicated fer romagnet-normal metal systems. We illustrate the theory by considering a no vel three-terminal device.
