TUNNELING MAGNETO-RESISTOR DEVICE FOR SENSING A MAGNETIC FIELD
摘要:
A tunneling magneto-resistor (TMR) device for sensing a magnetic field includes a first TMR sensor having a first MTJ (magnetic tunneling junction) device and a second MTJ device connected in parallel. Each of the first and second MTJ devices has a pinned layer and a free layer. The pinned layer of each of the first and second MTJ devices has a pinned magnetization at a first pinned direction. The free layers of the first and second MTJ devices have a first free magnetization parallel to and a second free magnetization anti-parallel to a first easy-axis respectively.
