Spin waves in the $(\pi ,0)$ magnetically ordered iron chalcogenide Fe${}_{1.05}$Te

O. J. Lipscombe, G. F. Chen, Chen Fang +7

We use inelastic neutron scattering to show that the spin waves in the iron chalcogenide Fe${}_{1.05}$Te display novel dispersion clearly different from those in the related iron pni…
