摘要
Arrays of Ni ferromagnetic nanowires of three different diameters (20, 40, and 170 nm) are obtained by electrodeposition into nanoporous alumina templates. Hysteresis curves parallel and perpendicular to the applied field are studied by angle dependent vector vibrating sample magnetometry. Hysteresis curves, from high remanence and coercivity for the smallest diameter, to nearly anhysteretic curves for the largest diameter, can be tuned by varying the diameter of the nanowires. The results show that the magnetic response of these arrays is a combination of coherent and incoherent rotation of magnetization of the nanowires.
