Jia, X. (author), Xia, K. (author), Bauer, G.E.W. (author)We compute thermal spin transfer (TST) torques in Fe-MgO-Fe tunnel junctions using a first principles wave-function-matching method. At room temperature, the TST in a junction with 3 MgO monolayers amounts to 10-7??J/m2/K, which is estimated to cause magnetization reversal for temperature differences over the barrier of the order of 10 K. The...journal article 2011

Jia, X. (author), Li, Y. (author), Xia, K. (author), Bauer, G.E.W. (author)Spin valves incorporating perpendicularly magnetized materials are promising structures for memory elements and high-frequency generators. We report the angular dependence of the spin-transfer torque in spin valves with perpendicular equilibrium magnetization computed by first-principles circuit theory and compare results with experiments by...journal article 2011
