Temperature effect on structural transformations in nanocrystalline cobaltfilms

The effect of annealing temperature on the structure and magnetic propertie s of nanocrystalline cobalt films has been studied by nuclear magnetic reso nance (NMR) and magnetometric (vibrational magnetometer) techniques. Interp retation of the experimental data demonstrates that the initial films have an amorphous-like structure due to the high degree of disordering in the in tergranular regions and nanoparticles. This structure transforms into the e quilibrium polycrystalline state through the formation of a number of inter mediate phases. (C) 2000 MAIK "Nauka/ Interperiodica".
