- Abstract
- We studied Fe double layer films on W(110) to investigate the role of strain relaxation in determination of the magnetic ground states. The spin reorientation transition (SRT) between perpendicular and in-plane magnetization takes place with varying density of dislocation lines as imaged with spin polarized scanning tunneling microscopy/spectroscopy. Unexpected domain wall orientation along W[001] and aperiodic magnetic domain patterns suggest that strain relaxation-induced domain has an easy axis along W[001] rather than W[1 (1) over bar0] in conjunction with the Dzyaloshinskii-Moriya interaction. Furthermore, we confirmed that the SRT can be suppressed by reducing the density of the dislocation lines with lower temperature annealing. (C) 2011 American Institute of Physics.
