Core–Shell and Bi-Segmented Cobalt–Nickel Nanorods Prepared by Electroless Deposition

A porous polymer loaded with segmented nanorods of magnetic metal is very promising for the design of novel microwave devices. Arrays of bi-segmented Ni/Co and core–shell Ni@Co rods were prepared by electroless deposition into porous of polycarbonate track-etched membrane. An intrinsic effective magnetic field of the magnetic composite nanorods aligned in the nonmagnetic template was studied by magnetization curves and ferromagnetic resonance (FMR). The effect of the interface boundaries for two types of bi-segmented rods with coaxial and along-axis Co/Ni segmentation to effective field was established.
