The size and space arrangement roles on coercivity of electrodeposited Co1−xCux nanowires

Abstract Magnetization curves with various magnetic field orientations and nanowire diameters were measured at room temperature. The measured coercivity as a function of angle ( θ ) between the field and wire axis reveals that the coercivity decreases with increasing value of θ for various nanowires. Theoretically, based on Monte Carlo simulation we investigated the magnetization reversal modes of the Co 1− x Cu x nanowires and obtained also the θ dependence of the coercivity. Comparing the simulated with the experimental results, we find that the magnetocrystalline anisotropy plays an important role on the magnetic properties of Co 1− x Cu x nanowires, and the magnetization reversal process in the Co 1− x Cu x nanowires could not be understood by the classical uniform rotation mode in the chain-of-sphere model.
