| Abstract: | The angular dependence of the
transverse and vortex modes in a magnetic nanotube is investigated as a function of the tube
geometry, by means of analytical calculations and numerical
simulations. A critical
radius defining the transition between vortex and transverse reversal modes is determined,
leading to low or high coercivity
modes just by varying the direction of the external field, in a fixed nanotube. |
