    Abstract

    In this study, the strain-induced change in the magnetic anisotropy of perpendicularly magnetized thin metals (TbFeCo and Pt/Co/Pt) deposited on a polyethylene naphthalate flexible substrate was investigated. The in-plane uniaxial tensile strain was reversibly applied up to 2%. The magnetic anisotropy was reversibly changed in both samples with applied streb. In the TbFeCo film, a marked change in magnetic anisotropy energy of 1.2 ' 105 J/m3 was observed. In the Pt/Co/Pt film, where the thickneb of Co was 2-4 monolayers, the streb-induced changes in interface and volume contributions to magnetic anisotropy were individually determined.
