Antiferromagnetism in NiO observed by transmission electron diffraction.
Neutron diffraction has been used to investigate antiferromagnetism since 1949. Here, we show that antiferromagnetic reflections can also be seen in transmission electron diffraction patterns from NiO. The diffraction patterns taken here came from regions as small as 10.5 nm, and such patterns could be used to form an image of the antiferromagnetic structure with a nanometer resolution.
