Spin Waves at High Temperature in the Parent Compound of the Superconductor F...
The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after... -
Mapping the Full Magnetic Dispersion of Multiferroic LuFe2O4
A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic"... -
The Structure of the High-Energy ¿Paramagnon¿ Excitations in La2-xSrxCuO4
A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most...
