New magnetic phase confirms theoretical predictions related to unconventional superconductivity

27 abril 2015

The emergence of a new magnetic phase with a square lattice before the onset of superconductivity is revealed in some iron arsenide compounds, confirming theoretical predictions of the effects of doping on magnetic interactions between the iron atoms and their relationship to high temperature superconductivity. Understanding the origin of thermodynamic phases is vital in developing a unified theory for the elusive microscopic mechanism underlying high-temperature superconductivity.
