Schematic representation of two inter-acting spin-transfer oscillators. Each pillar is composed by a free magnetic layers with vortex, a non magnetic spacer, and a SAF polarizer. Red arrows indicates the direction of spin polarization created by the polarizer. The nanopillars have a diameter D = 200 nm and are separated by a distance L. The parameters X1 and X2 define the cores positions.
