Spin transport in ferromagnetic/normal-metal tunnel junction arrays

2012

Published version of an article in the journal: Physical Review B. Also available from the publisher:http://dx.doi.org/10.1103/PhysRevB.85.094421 An array of alternating ferromagnetic and normal-metal islands separated by small tunnel junctions is theoretically investigated in the sequential tunneling regime. A numerical Monte Carlo method is used to calculate the transport properties. The spin-dependent tunneling currents give rise to nonequilibrium spin accumulation on the normal island. The tunneling magneto resistance (TMR) is calculated for a large range of array parameters. The TMR oscillates with bias voltage and can become negative for certain array parameters. We show that the long…
