A new magnetic logic overcomes the major limitations of field programmablegate arrays while having a 50% smaller unit cell than conventional designsutilizing magnetic tunnel junctions with one Heusler alloy electrode. Theseshow positive and negative TMR values at different bias voltages at roomtemperature which generally adds an additional degree of freedom to allspintronic devices
