Short summary

In magnetic reconnection in collisionless plasmas, a quadrupole structure of the magnetic field component in the direction of current supporting the reconnecting magnetic field is generated down to electron scales. This paper shows that the magnetic field can develop a "nested structure of quadrupoles" at the electron scales and identifies the nested structure in Cluster observations. Results are useful in interpreting the electron physics in observations, in particular by the NASA/MMS mission.
