Restrictions on modeling spin injection by resistor networks
arXiv:0805.4757 · doi:10.1088/0268-1242/23/11/114015
Abstract
Because of the technical difficulties of solving spin transport equations in inhomogeneous systems, different resistor networks are widely applied for modeling spin transport. By comparing an analytical solution for spin injection across a ferromagnet - paramagnet junction with a resistor model approach, its essential limitations stemming from inhomogeneous spin populations are clarified.
