Microstructural and magnetic properties of metallic thin films obliquely sputtered on polymer

Effect of annealing on the size dependent deformation behavior of thin cobalt films on flexible substrates

“…Cobalt is a common material in magnetic storage devices [1] and can be used in form of cobalt oxide as supercapacitors [2] or as the anode material in lithium ion batteries [3]. Due to the advanced miniaturization of these devices and the consequential geometrical constraints, thin cobalt films exhibit a completely different magnetic and mechanical behavior compared to the bulk material [4][5][6][7][8]. For example, nanocrystalline cobalt shows a two to three times higher yield strength and enhanced ductility at low strain rates compared to polycrystalline cobalt [7].…”

Study of obliquely deposited thin cobalt films

“…Nevertheless, studies which report on correlation of the magnetic domain structure of these films with their morphological structure are in fact rare. Frankly speaking, we know only a few such studies [5][6][7][8][9][10]. Moreover, to our knowledge, observations of the morphological structure of obliquely deposited thin cobalt films have not yet been carried out simultaneously by TEM and AFM.…”

Reorientation of magnetic anisotropy in obliquely sputtered metallic thin films

“…2͒. In a recent work 11 we established from SEM investigations that at large incidence angle, the film microstructure consists of columns with an ellipsoidal shape, well separated from each other. The columns are oriented following the longitudinal direction.…”
