Effect of the underlayer on the elastic parameters of the CoFeB/MgO heterostructures

Abstract We investigated the thermally induced surface acoustic waves in CoFeB/MgO heterostructures with different underlayer materials. Our results show a direct correlation between the density and elastic parameters of the underlayer materials and the surface phonon dispersion. Using finite elemen...
