Spin waves in the $(\pi,0)$ magnetically ordered iron chalcogenide Fe$_{1.05}$Te
Spin waves
2010/11/22
We use inelastic neutron scattering to show that the spin waves in the iron chalcogenide Fe1.05Te display novel dispersion clearly different from those in the related iron pnictide systems. By fitting...
Spin waves in magnetic quantum wells with Coulomb interaction and $sd$ exchange coupling
Spin waves magnetic quantum wells Coulomb interaction

We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work,
we introduce equ...
