研究了如何通过诱导脉冲电流来控制受限电流路径电流垂直面巨磁阻型(CCP-CPP GMR)传感器的纳米针孔结构。我们发现，通过施加最佳的脉冲电流，可以在降低传感器电阻的情况下提高磁阻比。这被认为是由于增大了纳米针孔面积和减小了针孔阻力所致。当施加过大的脉冲电流时，由于CPP-GMR传感器的热降解，导致MR比和传感器电阻降低。
We investigated how to control the nano-pinhole structure of a confined-current-path current-perpendicular-to-plane giant magnetoresistive (CCP-CPP GMR) sensor by inducing pulse current. We found an improved MR ratio with reduced sensor resistance by applying an optimal pulse current. This was assumed to be due to the enlarged nano-pinhole area and reduced pinhole resistance. When excessive pulse current was applied, the MR ratio and sensor resistance decreased because the CPP-GMR sensor degraded thermally.
