Spin Waves at High Temperature in the Parent Compound of the Superconductor FeSexTe1-x (x=0)

DOI

The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after magnetic order is suppressed by doping the antiferromagnetic parent compounds. We have recently investigated the spin waves in both the magnetically ordered parent compounds of the iron chalcogenide system, FeTe, and iron pnictide systems. Though these two systems are in many ways similar, the parent compounds have different magnetic structures and exchange couplings. We propose to study the magnetic excitations in FeTe above the ordering temperature TN, to investigate the paramagnetic behavior of the magnetic excitations. There is also a structural phase transition at TN, and we would like to investigate whether the anisotropy we found at low temperature persists above the magnetic and structural phase transition.
