Abstract :
We investigated current perpendicular-to-the-plane giant magnetolresistive (CPP-GMR) films deposited with oblique incidence. The obliquely deposited free layer increased the MR ratio and the RA slightly, even though small asymmetric distribution of tilted angles was seen in our cross-sectional observation. In contrast, the MR ratio decreased with the obliquely deposited Cu spacer. Therefore, oblique deposition for CPP-GMR films is an effective method for increasing electron scattering at the obliquely deposited magnetic layer
