Abstract
Hysteresis curves are investigated for finite arrays of ferromagnetic nanodots subject to the dipole-dipole interaction (,13). Spin arrangements up to are presented, which indicate the onset of bulklike behavior associated with odd and even systems. The effect of field misalignment on the hysteresis loops is also studied for ,6. The area of the hysteresis loop is studied as a function of . approximately scales as for odd and as for even.
