AbstractLateral surface induced effects on cylindrical amorphous Co nanowires have been studied using the Monte Carlo method. The simulation results show that lateral surface induced uniaxial anisotropy has a strong influence on the magnetization of nanowires with diameters smaller than 5 nm when its value exceeds 5.0 × 105 erg cm-3. It has been found that a unique transformation from a homogeneous magnetic state to a non-uniform spin precession extension wave occurs on increasing the temperature. Moreover, the uniaxial anisotropy has little effect on the hysteresis loop when the applied magnetic field is parallel to the revolution axis of the nanowire, whereas for an applied transverse magnetic field, the influence is larger. © 2009 IOP Publishing Ltd.
