Boltzmann test of Slonczewski’s theory of spin-transfer torque
Boltzmann test of Slonczewski’s theory of spin-transfer torque
We use a matrix Boltzmann equation formalism to test the accuracy of Slonczewski's theory of spin-transfer torque in thin-film heterostructures where a non-magnetic spacer layer separates two non-collinear ferromagnetic layers connected to non-magnetic leads. When applicable, the model predictions for the torque as a function of the angle between the …
