Paper Title:
Magnetic Properties of Various Thick Co-Fe Circular Dot Arrays
  Abstract

We have studied the magnetic properties of Co-Fe circular dot arrays with various thicknesses and diameters in order to determine the optimum thickness and diameter of these dot arrays with a single-domain state for the transmission of spin information. For the thickness of 10 nm, the magnetic state changes from a multi-domain state to a closure-domain state and further to a single-domain state with decreasing diameter. On the other hand, for the thickness of 30 nm and 50 nm, all magnetic states are in a vortex state, regardless of the diameter. From these results, it is found that the optimum thickness and diameter of Co-Fe circular dots with a single-domain state are, respectively, 10 nm and less than 100 nm.
