  • Title: Thickness dependent structural, magnetic and transport properties of nanostructured cobalt thin films.
    Author: Sharma A, Tripathi S, Brajpuriya R, Shripathi T, Chaudhari SM.
    Journal: J Nanosci Nanotechnol; 2007 Jun; 7(6):2041-5. PubMed ID: 17654988.
    Abstract:
    This paper presents structural, magnetic, and transport properties measurements carried out on Co thin film as a function of thickness. The structure of the Co thin film changes from amorphous to nano-crystalline with the increase in film thickness. The corresponding magnetic and transport measurements show drastic changes in coercivity, saturation field and resistivity value as a function of Co film thickness. Observed magnetization and resistivity behaviour is mainly attributed to the (i) Change in crystal structure, (ii) stress relaxation, (iii) grain growth as revealed by X-ray diffraction (XRD), and atomic force microscopy (AFM) measurements.
