A current passing through the MTJ gets spin-polarized by the pinned layer, and exerts a torque on the free layer. Figure 1: Experimental set-up and magnetoresistance. The working principles of the ...

This enables them to go a step further and extend the range of bias currents to the value where the spin-transfer torque actually switches the free magnetic moment of an MTJ. Similar to Sankey et al., ...

In this article, we report the first experimental demonstration of sub-20-nm magnetic tunnel junction (MTJ) cells for investigating the downscaling feasibility of spin-transfer torque (STT) MRAM, one ...

Crocus Technology’s STT-based (Spin Transfer Torque) MRAM technology looks to ... current required at the magnetic tunnel junction (MTJ) to write data by a factor of five (Fig.

This development is likely to be a significant contribution to reducing the die size of spin transfer torque MRAMs (STT-MRAM), making their commercialisation more practical. Because MTJs use magnetic ...

What are Magnetic Tunnel Junctions? Magnetic tunnel junctions (MTJs) are nanoscale devices that consist of two ferromagnetic layers separated by a thin insulating tunnel barrier. The electrical ...

The torque excites oscillations in the magnetization and if strong enough can cause the magnetization direction to flip. In the case of a spin valve or magnetic tunnel junction (MTJ), a magnetic layer ...
