ABSTRACT
Spin order in hexagonal close packed cobalt nanodisk rows is quantitatively determined by off-axis electron holography. Periodic variation in the density of the local magnetic flux shows features of a spiral spin arrangement along the row axis, resulting from a tilted magnetic moment of nanoparticles with respect to the nanodisk axis.
