Claim Text:
1. Magnetic logic unit (MLU) cell comprising: a first magnetic tunnel junction and a second magnetic tunnel junction, each magnetic tunnel junction comprising a first magnetic layer having a first magnetization, a second magnetic layer having a second magnetization, and a barrier layer between the first and second magnetic layers; a strap, electrically connecting the magnetic tunnel junction in series with the second magnetic tunnel junction; and a field line for passing a field current such as to generate an external magnetic field adapted to adjust the first magnetization; the first and second magnetic layers and the barrier layer being arranged such that the first magnetization is magnetically coupled antiparallel with the second magnetization through the barrier layer; the MLU cell further comprising a biasing device arranged for applying a static biasing magnetic field oriented substantially parallel to the external magnetic field such as to orient the first magnetization at about 90° relative to the second magnetization, the first and second magnetizations being oriented symmetrically relative to the direction of the external magnetic field.
