New Ideas for Understanding the Structure and Magnetism in AgF : Prediction of Ferroelasticity.

In the search for new high-temperature superconductors, it has been proposed that there are strong similarities between the fluoroargentate AgF and the cuprate La CuO . We explored the origin of the possible layered structure of AgF by studying its parent high-symmetry phase and comparing these results with those of a seemingly analogous cuprate, CuF . Our findings first stress the large differences between CuF and AgF .
