Controlling Dipolar Interaction Effect in Two-Dimensional Magnetic Nanostructures
Manish Anand
Abstract:We investigate the dependence of magnetic properties on the out-of-plane disorder strength ∆, dipolar interaction strength h d in two-dimensional (l x × l y ) ensembles of nanoparticles using numerical simulations. Such positional defects are redundantly observed in experiments. The superparamagnetic character is dominant with negligible and weak interaction strength h d , irrespective of ∆ and aspect ratio of the system A r = l y /l x . The double-loop hysteresis curve, characteristics of antiferromagnetic co… Show more
