Temperature dependent scattering rate and optical mass of ferromagnetic metallic manganites
J. R. Simpson, H. D. Drew, V. N. Smolyaninova +4
We report on the optical properties of the hole-doped manganites La_0.7Ca_0.3MnO_3 and La_0.7Ca_0.3MnO_3. Transmission and reflection of thin films are measured in the infrared at…
Infrared Hall effect in high Tc superconductors: Evidence for non-Fermi liquid Hall scattering
J. Cerne, M. Grayson, D. C. Schmadel +5
Infrared (20-120 cm-1 and 900-1100 cm-1) Faraday rotation and circular dichroism are measured in high Tc superconductors using sensitive polarization modulation techniques. Optimal…
Mid-infrared Hall effect in thin-film metals: Probing the Fermi surface anisotropy in Au and Cu
J. Cerne, D. C. Schmadel, M. Grayson +3
A sensitive mid-infrared (MIR, 900-1100 cm-1, 112-136 meV) photo-elastic polarization modulation technique is used to measure simultaneously Faraday rotation and circular dichroism…
