考虑非共线自旋积累，发展了正常金属-铁磁混合电路中的自旋输运理论。通过电阻元件的自旋输运由4个电导参数描述。这些电导的微观表达式中导出的散射矩阵和明确计算简单的模型。将电路理论应用于附着在铁磁储层上的二端和三端器件。
A theory of spin-transport in hybrid normal metal-ferromagnetic electronic circuits is developed, taking into account non-collinear spin-accumulation. Spin-transport through resistive elements is described by 4 conductance parameters. Microscopic expression for these conductances are derived in terms of scattering matrices and explicitly calculated for simple models. The circuit theory is applied to 2-terminal and 3-terminal devices attached to ferromagnetic reservoirs.
