Magnetic logic unit (MLU) cell and amplifier having a linear magnetic signal

摘要

The present disclosure concerns magnetic logic unit (MLU) cell (1) comprising a first and second magnetic tunnel junction (2), each comprising a first magnetic layer (21) having a first magnetization (210), a second magnetic layer (23) having a second magnetization (230), and a barrier layer (22); and a field line (4) for passing a field current (41) such as to generate an external magnetic field (42) adapted to adjust the first magnetization (210); the first and second magnetic layers (21, 23) and the barrier layer (22) being arranged such that the first magnetization (210) is magnetically coupled antiparallel with the second magnetization (230) through the barrier layer (22); the MLU cell (1) further comprising a biasing device (50) arranged for applying a static biasing magnetic field (53) oriented substantially parallel to the external magnetic field (42) such as to orient the first magnetization (210) at about 90° relative to the second magnetization (230), the first and second magnetizations being oriented symmetrically relative to the direction of the external magnetic field (42).
