چکیده (انگلیسی):

The evolution and magnetic behaviour of NiO–Ni(OH)2 core–shell
nanostructures with different thicknesses of the hydroxide shell
have been studied. The nickel hydroxide shell is found to alter the
magnetic characteristics of nickel oxide at low temperatures and
explains the origin of the exchange bias effect due to the antiferromagnetic
NiO core and a ferromagnetic nickel hydroxide shell.
