Abstract
A 3-dimensional micromagnetic model that includes eddy currents was used to determine critical particle size and conductivity range that leads to pronounced eddy current effects on magnetization reversal of magnetic nano-structures. It was concluded that the field created by the eddy currents causes an additional torque which initiates magnetization reversal. In the intermediate state of magnetization reversal, eddy currents may lead to a critical slowing down.
