Abstract
A magnetic logic unit (MLU) cell includes a first and second magnetic tunnel junction, each including a first magnetic layer having a first magnetization, a second magnetic layer having a second magnetization, and a barrier layer; 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 are arranged such that the first magnetization is magnetically coupled antiparallel with the second magnetization through the barrier layer. The MLU cell also includes 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.
