Enhanced triplet Andreev reflection off a domain wall in a lateral geometry
Joern N. Kupferschmidt, Piet W. Brouwer
We find that the triplet Andreev reflection amplitude at the interface between a half-metal and an s-wave superconductor in the presence of a domain wall is significantly enhanced…

Spin torque from tunneling through impurities in a magnetic tunnel junction
Turan Birol, Piet W. Brouwer
We calculate the contribution to the spin transfer torque from sequential tunneling through impurities in a magnetic tunnel junction. For a junction with weakly polarized ferromagn…
