One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or...

Understanding the magnetic exchange coupling and fundamental Hamiltonian of the parent compound of FeAs-based superconductors is extremely important, because such information...

The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after...
