Sharp optical phonon softening close to optimal doping in LaBaCuO
Matteo D'Astuto, Guy Dhalenne, Jeff Graf +6
We report a direct observation of a sharp Kohn-like anomaly in the doubly degenerate copper-oxygen bond-stretching phonon mode occurring at in La$_…
Bond stretching phonon softening and angle-resolved photoemission kinks in optimally doped Bi2Sr1.6La0.4Cu2O6 superconductors
J. Graf, M. d'Astuto, C. Jozwiak +7
We report the first measurement of the optical phonon dispersion in optimally doped single layer Bi2Sr1.6La0.4Cu2O6+delta using inelastic x-ray scattering. We found a strong soften…
Coexistence of sharp quasiparticle dispersions and disorder features in graphite
S. Y. Zhou, G. -H. Gweon, C. D. Spataru +4
Angle resolved photoelectron spectroscopy (ARPES) on azimuthally disordered graphite demonstrates that sharp quasiparticle dispersions along the radial direction can coexist with a…
Mapping the spin-dependent electron reflectivity of Fe and Co ferromagnetic thin films
J. Graf, C. Jozwiak, A. K. Schmid +2
Spin Polarized Low Energy Electron Microscopy is used as a spin dependent spectroscopic probe to study the spin dependent specular reflection of a polarized electron beam from two…
