Anisotropic effect of Cd and Hg doping on the Pauli limited superconductor CeCoIn5.
We studied the effect of impurity on the first order superconducting (SC) transition and the high field-low temperature (HFLT) SC state of CeCoIn5 by measuring the specific heat of CeCo(In1-xCdx)_{5} with x=0.0011, 0.0022, and 0.0033 and CeCo(In1-xHgx)_{5} with x=0.000 16, 0.000 32, and 0.000 48 at temperatures down to 0.1 K and fields up to 14 T. Cd substitution rapidly suppresses the crossove...
متن کاملNonlinear paramagnetic magnetization in the mixed state of CeCoIn5
Torque and magnetization measurements in magnetic fields H up to 14T were performed on CeCoIn5 single crystals. The amplitude of the paramagnetic torque shows an H dependence in the mixed state and an H dependence in the normal state. In addition, the mixedstate magnetizations for both H k c and H k ab axes show anomalous behavior after the subtraction of the corresponding paramagnetic contribu...
متن کاملOptical conductivity of the heavy fermion superconductor CeCoIn5
The electrodynamic response of the heavy fermion compound CeCoIn5 is studied via infrared spectroscopy. Below 100 K the high temperature Drude-like conductivity evolves into two distinct components. At low energies a narrow mode is observed which is characteristic of the response of heavy quasiparticles. At higher energies a gap structure emerges with 2D;600 cm ~75 meV!. Examination of the fine...
