Scheme of our coupled STNOs system.

Two spin valve nanopillars with 2R = 200 nm diameter separated by a distance L = 100 nm. Each pillar contains a NiFe(4 nm)/Cu(10 nm)/NiFe(15 nm) spin valve (NiFe = Ni₈₁Fe₁₉) and a vortex is present in each 15 nm NiFe layers. The current is injected in parallel into the two pillars.
