SPIN TORQUE-TYPE MAGNETIC SENSOR |
摘要 |
The present invention is directed to a magnetic sensor using a spin transfer torque device, including a spin transfer torque device configured such that the magnetization direction thereof is varied by current, a bipolar pulse source configured to apply bipolar pulses to the spin transfer torque device in order to control the coercive field and sensitivity of the spin transfer torque device, and a signal processing unit configured to calculate magnetic susceptibility or magnetic resistance by counting the parallel (P) or anti-parallel (AP) states of the spin transfer torque device in response to the applied bipolar pulses. |
