摘要
This communication demonstrates the assembly of superparaferromagnetic colloidal nanoparticles into one-dimensional (1D) nanochain structures using an external magnetic field at room temperature, which were surrounded and linked by the amorphous carbon on the surface of nanoparticles. It is suggested that these nanochains have a fixed distance between adjacent colloidal particles and can diffract purple visible light (404 nm) under the induction of an external magnetic field.
