Abstract

Abstract The fabrication of necklace-shaped assembly of nanospheres under a magnetic field is reported, in which necklace-shaped assembly of single-crystal Ni-ferrite nanospheres is induced by the magnetic force. This nanostructure is a type of oriented assembly of the nanospheres, which is confirmed by the transmission electron microscopy (TEM) and scanning electron microscopy (SEM) analysis. The result of vibrating sample magnetometer (VSM) shows the correlation between the magnetic properties and crystallinity of the magnetic nanospheres.
