Size dependence of tunneling magnetoresistance in self-assembled nanoparticle arrays

In this paper, size dependence of tunneling magneto resistance (TMR) in nano particle arrays was studied with Monte Carlo simulation and resistor network model. When the electrode was applied along the X-axis, TMR increased as the length LJ increasing and then decreased in particle arrays, while TMR decreased with increasing length LJ as the electrode was along the Y-axis.
