Effects of magnetic field on hydrothermal growth of Cu–Ni system

The induction effects of applied external magnetic field on the morphology, composition and magnetic properties of copper-nickel system grown with hydrothermal method have been investigated in the presence of polyvinyl pyrrolidone (PVP). The products’ phases and morphologies are characterized by X-ray diffractometer (XRD) and field emission scanning electronic microscopy (FESEM). Magnetic measurements reveal that the introduction of magnetic field could lead to the enhancement of magnetic parameters, which implies that the magnetic field could exert influences on the nucleation and domain structure of particles.
