KMnF3, I wrote a theory of antiferroelectric antiferromagnets and presented it to Portis with great pride.

Magnetic atoms can have their moments all ordered in the same direction in each domain (ferromagnetism), with alternating "up" and "down" moments of the same size (simple antiferromagnets) or with more complicated patterns including different magnetic sublattices (ferrimagnets, etc).

However, Phil Anderson's idea that the phenomenology of the cuprates might be related to the known behavior of 1-dimensional antiferromagnets, which has a beautiful formal relationship to the fractional quantum hall ground state discovered by Duncan Haldane and Sriram Shastry, is still very intriguing, especially since the particles carrying fractional quantum numbers in the latter system, which we call spinons, are relativistic.

"And, in fact, we have been able to use it to explain experimental observations on heavy fermion metals, including both the antiferromagnets as well as the less well understood ferromagnetic materials."
