Query: Molecule Induced Strong Exchange Coupling between Ferromagnetic
  Electrodes of a Magnetic Tunnel Junction   Multilayer edge molecular spintronics device (MEMSD) approach can produce
novel logic and memory units for the computers. MEMSD are produced by bridging
the molecular channels across the insulator, in the exposed edge region(s) of a
magnetic tunnel junction (MTJ). The bridged molecular channels start serving as
the dominant exchange coupling medium between the two ferromagnetic electrodes
of a MTJ. Present study focus on the effect of molecule enhanced exchange
coupling on the magnetic properties of the MTJ. This paper shows that
organometallic molecular clusters (OMCs) strongly increased the magnetic
coupling between the two ferromagnetic electrodes. SQUID magnetometer showed
that OMCs transformed the typical hysteresis magnetization curve of a
Co/NiFe/AlOx/NiFe MTJ into linear one. Ferromagnetic resonance studies showed
that OMC bridges affected the two fundamental resonance peaks of the
Co/NiFe/AlOx/NiFe MTJ. According to magnetic force microscopy, OMCs caused the
disappearance of magnetic contrast from the Co/NiFe/AlOx/NiFe tunnel junction
area. These three independent and complimentary experiments, suggested the
development of extremely strong interlayer exchange coupling. This work
delineated a practical route to control the exchange coupling between
ferromagnetic electrodes. Ability to tailor magnetic coupling can lead to the
development of molecule based quantum computation device architecture.
