摘要：

The magnetic and electrical properties and the temperature dependence of these properties of cobalt films prepared at high condensation rates (10(5)-10(6) Angstrom/s) are investigated. Incremented annealing reveals several nonequilibrium states of cobalt in transition from the as-prepared metastable structure to the ordinary hcp structure. The anomalies of the properties are analyzed from the standpoint of the nanocrystalline state of the samples. Model concepts of microcluster formations in the investigated films are also discussed.
