STUDY OF STRAIN-DEPENDENT MAGNETIC PROPERTIES OF CoFeB/Pd MULTILAYER FILMS ON POLYIMIDE SUBSTRATE
Main Article Content
Abstract
Recently, magnetic thin films deposited on flexible substrates have attracted significant interest from the scientific community due to their ability to tune magnetic properties through stress/strain. This work presents experimental results on CoFeB/Pd multilayer ferromagnetic thin films with different thicknesses of 0.4 nm and 1.3 nm. Bending strain was generated using curved molds with varying diameters, combined with magneto-optical Kerr effect measurements to observe changes in magnetic properties. The normalized remanent magnetization and coercivity parameters of the multilayer films under different strain levels were analyzed in detail, revealing a pronounced dependence of magnetic properties on the strain applied to the flexible polyimide substrate.
Keywords
