A study of nucleation, growth, texture and phase formation of electrodeposited cobalt layers and the influence of magnetic fields

Magnetic field effects on the initial stages of electrodeposition processes

“…On the other hand, there are only few papers [12][13][14] which investigated the initial stages of electrocrystallization, such as nucleation and underpotential deposition (UPD) processes in the B field, because the general tenet is that the chief magnetic field effects are related to masstransport (MHD convection) and that molecular processes are hardly affected [15][16][17][18]. In our previous work [19], the surface morphology at the initial stage of Cu deposition was investigated by AFM.…”

Growth and magnetic properties dependence of the Co–Cu/Cu films electrodeposited under high magnetic fields

“…Though the hexagonal closed-packed structure is the most stable phase of bulk cobalt up to 420 C [26], experimental data reveal the coexistence of both fcc and hcp phases of Co in all CoeCu/Cu samples. Furthermore, a clear designation of the presence of fcc or hcp Co phase at 2q angle around 44 is not easy due to the overlap of both diffraction lines: Co fcc e 44.217 (JCPDS 15e0806) and Co hcp e 44.763 (JCPDS 05e0727).…”

Electrocrystallisation of CoFe alloys under the influence of external homogeneous magnetic fields—Properties of deposited thin films

“…This then leads to a privileged grow direction. It was proposed by Krause et al [45] that adsorption of hydrogen could affect the growth mode of electrodeposited Co and a shift in the structure from fcc to hcp has been observed. The columnar growth mode in a perpendicular magnetic field could also induce stray fields above the columns.…”
