3. Spin transfer torque

Applying a magnetic field to a ferromagnetic nanoelement changes its direction of magnetization, and therefore its resistance in the case of a GRM or TRM element. This makes it possible, for example, to produce magnetic field sensors (§ 5 ). On the other hand, the use of magnetic fields to reverse magnetization poses a problem in spintronic devices such as MRAM memories (§
