Similarly, the new iron-based high temperature superconductors exhibit symmetry breaking competing phases in the form of a tetragonal to orthorhombic structural transition preceding or coincident with the development of collinear spin density wave SDW in the undoped parent compounds, and superconductivity arises when both transitions are suppressed via doping. One exception is the remakable behavior in a nodal system P-doped Ba identified by Mizukami et al. Remarkably, we observe that this anisotropy manifests a broken symmetry in the orbital degree of freedom via a large splitting of the d xz and d yz bands. Bardeen; L. Similarly, at a fixed temperature below the critical temperature, superconducting materials cease to superconduct when an external magnetic field is applied which is greater than the critical magnetic field. In Februaryan iron-based family of high-temperature superconductors was discovered. Kreisel, S.
