Title:
Measurement of Strong Phonon Softening in {{Cr}} with and without {{Fermi}}-Surface Nesting by Inelastic x-Ray Scattering 
Abstract:
Nesting of the Fermi surface can soften and broaden phonons at the nesting wave vectors. However, huge electron-phonon anomalies unexpected from the experimental topology of the Fermi surface have been reported in copper oxide superconductors and their origin remains enigmatic. Here we present results of inelastic x-ray scattering measurements that uncovered similarly pronounced softening of phonons in chromium that occur far from the nesting wave vectors of the Fermi surface. The softening appe...    »
