The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
The search for long range exchange interactions in the S=1 square lattice ant...
Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized... -
The relationship between the pseudogap and magnetic excitations in La2-xSrxCuO4
This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the... -
Probe spin excitations in heavily overdoped BaFe2-xNixAs2
Spin excitations is correlated with superconductivity in high Tc superconductors. The spin excitations in La2-xSrxCuO4 superconductors become weaker in overdoped region and... -

Effect of electron doping on the magnetic dynamics of the d^4 Mott insulator ...
Oxides containing heavy transition-metal ions with four d electrons (d^4) surrounded by an octahedron of oxygen ions have recently been predicted to display a novel type of... -
High precision measurements of the spin wave dispersion in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. Despite decades... -

The collective spin excitations in the electron-doped superconductor BaFe2-xC...
We propose to measure the collective spin excitations over a wide energy range in BaFe2-xCoxAs2 (x=0.22). This compound is one of the FeAs based superconductors which have... -
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... -
Spin Excitations and "Hourglass" Dispersion in the Model High-Tc superconduct...
The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to... -
Hourglass dispersion in overdoped manganites
Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close...
