摘要：

ConclusionThis study demonstrates the manipulation of the pinning direction in MTJs with varying tIrMn under the zero magnetic field cooling process, which results from the competition between the exchange bias coupling and interlayer coupling through the SAF layer. Our results clarify the coupling mechanism for determining the pinning direction of MTJs under the zero magnetic field cooling treatment, which can guide the design scheme of full Wheatstone bridge-based TMR sensors.
