This work studies the magnetic behavior of ZnO nanoparticles capped
with different organic molecules and showing room-temperature
ferromagnetism (RTFM). Of particular significance is the
combination of element-specific X-ray absorption spectroscopy (XAS)
and X-ray magnetic circular dichroism (XMCD) techniques, which
demonstrates the intrinsic occurrence of RTFM in these systems and
indicates that it is not related to the 3-D states of the metallic
cation but is relayed along the conduction band of the
semiconductor. The discovery of room-temperature ferromagnetism
(RTFM) in semiconductors holds great promise in future spintronics
technologies. Further results presented here include O K-edge XMCD
studies, which demonstrate that the oxygen ions have a
ferromagnetic response in these ZnO-based systems, providing the
first direct support for claims regarding the appearance of oxygen
ferromagnetism in oxide semiconductors at the nanoscale.
