| Popis: | In-situ scanning tunneling microscopy STM and in-situ alternating gradient field magnetometry AGFM are used in . combination to characterize the structure and magnetic behavior of CorAu 111 layers electrodeposited from CoSO4 solutions, with anions X s Cl y and SCN y added in amount traces. In the Cl y solution, the 2-D growth process is briefly y . recalled. In the thiocyanate SCN solution, preliminary observations show that nanometer clusters accumulate on top of a . . Co underpotential deposition UPD monolayer. Both structures solutionrCorAu 111 exhibit perpendicular magnetic . )) yy anisotropy PMA for a Co thickness t F t , with t ; 2 ML in the Cl solution and ; 4-5 ML in the SCN one. Results are briefly discussed in light of classical models for PMA in ultrathin films. q 2000 Elsevier Science B.V. All rights reserved. |
