摘要：

The magneto-mechanical coupling effect of amorphous Co40Fe40B20 (CoFeB) films (10-200 nm) on flexible polyethylene terephthalate substrates were investigated in detail. The normalized remanent magnetization (M-r/M-s) of CoFeB films changes significantly (up to 62%) under small tensile or compressive strain. Moreover, the thickness dependence of the magneto-mechanical coupling effect for the flexible CoFeB films was demonstrated. These results provide important information for the development of CoFeB-based magnetic tunnel junction used in flexible spintronic devices. (C) 2014 AIP Publishing LLC.
