Crossover Phase Diagram of 2D Heisenberg Ferro- and Antiferromagnets
Alexander Sokol, Norbert Elstner, Rajiv R. P. Singh
We propose a single crossover phase diagram applicable to 2D collinear Heisenberg antiferromagnets (AFMs) and ferromagnets (FMs), and show that the scaling regimes of AFMs and FMs…

Magnetic Behavior of the Cuprate Superconductors
Alexander Sokol
I review recent work on magnetic dynamics of the high temperature superconductors using a model that combines two weakly interacting species of low-energy excitations: the antiferr…
