Abstract
An intrinsic spin-dependent Seebeck effect in the linear tunneling transport regime of magnetic tunneling junctions (MTJs) was discovered recently. This effect leads to a nonlinear correction of Ohm's law in the dc response. We analyze this intrinsic magneto-thermoelectrical effect for MTJs with different MgO barrier (t(b) = 0.7 - 1.35 nm) thicknesses. We report strong intrinsic effects in MTJs with thin MgO barriers (1189%), upon reversal of the magnetization of the two CoFeB layers. Such large effects are promising for useful spin caloritronic devices, integrating charge, heat, and spin tunnel transport. (C) 2013 AIP Publishing LLC.
