Small magnetic structures have attracted a great deal of attraction
owing to their special transport and magnetic properties. In a magnetic quantum dot array,
the interdot exchange interaction leads to alignment of individual magnetization. In this
paper, starting from the interaction energy between the neighboring dots, we set up an
equation of motion for the magnetization. We use bosonic operators combined with the
Holstein-Primakoff transformations in the semiclassical limits and arrive at Nonlinear
Schrodinger equation. Localized solutions called solitons are identified for the collective
excitations, which could be harnessed for data transfer.
