Neki aspekti taloženja nikla u prisustvu magnetnog polja

Nickel deposits obtained from a Watt solution both without and with a perpendicularly oriented magnetic field were examined by scanning electron microscopy (SEM). The nickel deposit obtained without an imposed magnetic field was very rough, with a clearly visible clustered structure. The nickel deposit obtained under a perpendicularly oriented magnetic field has a very developed dendritic structure, which can be denoted as arboreous – bead dendritic structure. The ob- served difference is essentially ascribed to the effect of a magnetic field on the magnetic properties of nickel.U ovom radu, talozi nikla dobijeni iz Vatovog rastvora su ispitani tehnikom skenirajuće elektronske mikroskopije. Taloženje je bilo izvedeno bez prisustva magnetnog polja, kao i u prisustvu vertikalno orijentisanog magnetnog polja. Talog nikla dobijen bez prisustva magnetnog polja je bio veoma hrapav, sa jasno vidljivim klasterima nikla. Talog nikla dobijen pod vertikalno orijentisanim magnetnim poljem je bio veoma razvijene dendritične strukture. Posmatrana razlika između ovih morfologija nikla je prvenstveno pripisana uticaju magnetnog polja na magnetne osobine nikla
