Far-infrared optical conductivity of CeCu2Si2
J. Sichelschmidt, A. Herzog, H. S. Jeevan +4
Journal ref.: J. Phys.: Condens. Matter 25, 065602 (2013): We investigated the optical reflectivity of the heavy-fermion metal CeCu2Si2 in the energy range 3 meV - 30 eV for temper…
Optical properties of iron-based superconductor LiFeAs single crystal
Byeong Hun Min, Jong Beom Hong, Jae Hyun Yoon +4
We have measured the reflectivity spectra of the iron based superconductor LiFeAs (Tc = 17.6 K) in the temperature range from 4 to 300 K. In the superconducting state (T < Tc), the…
Optical study of archetypical valence-fluctuating Eu-systems
V. Guritanu, S. Seiro, J. Sichelschmidt +5
We have investigated the optical conductivity of the prominent valence fluctuating compounds EuIr2Si2 and EuNi2P2 in the infrared energy range to get new insights into the electron…
Existence of Heavy Fermions in the Antiferromagnetic Phase of CeIn3
Takuya Iizuka, Takafumi Mizuno, Byeong Hun Min +2
We report the pressure-dependent optical conductivity spectra of a heavy fermion (HF) compound CeIn3 below the Neel temperature of 10 K to investigate the existence of the HF state…
Optical study of charge instability in CeRu2Al10 in comparison with CeOs2Al10 and CeFe2Al10
Shin-ichi Kimura, Takuya Iizuka, Hidetoshi Miyazaki +7
The anisotropic electronic structure responsible for the antiferromagnetic transition in CeRuAl at the unusually high temperature of = 28 K was studied using optic…
Temperature- and Magnetic-Field-Dependent Optical Properties of Heavy Quasiparticles in YbIr2Si2
T. Iizuka, S. Kimura, A. Herzog +4
We report the temperature- and magnetic-field-dependent optical conductivity spectra of the heavy electron metal YbIrSi. Upon cooling below the Kondo temperature ($T_{\rm K…
