Pressure-induced change of the pairing symmetry in superconducting CeCu2Si2
E. Lengyel, M. Nicklas, H. S. Jeevan +5
Low-temperature (T) heat-capacity measurements under hydrostatic pressure of up to p=2.1 GPa have been performed on single-crystalline CeCu2Si2. A broad superconducting (SC) region…
Enhancement of Nuclear Spin-Lattice Relaxation Rate and Spin Susceptibility due to Valence Fluctuations -Origin of Anomalously Enhanced Wilson Ratio in Ce and Yb Systems-
Shinji Watanabe, Kazumasa Miyake
We show theoretically that the nuclear spin-lattice relaxation rate (T_1T)^{-1} and the spin susceptibility exhibit divergent behaviors toward zero temperature at the quantum criti…
Valence Fluctuations Revealed by Magnetic Field Scan: Comparison with Experiments in YbXCu_4 (X=In, Ag, Cd) and CeYIn_5 (Y=Ir, Rh)
Shinji Watanabe, Atsushi Tsuruta, Kazumasa Miyake +1
The mechanism of how critical end points of the first-order valence transitions (FOVT) are controlled by a magnetic field is discussed. We demonstrate that the critical temperature…
Coupled SDW and Superconducting Order in FFLO State of CeCoIn
K. Miyake
The mechanism of incommensurate (IC) spin-density-wave (SDW) order observed in the Flude-Ferrell-Larkin-Ovchinnikov (FFLO) phase of CeCoIn is discussed on the basis of new mode…
Magnetic-Field Control of Quantum Critical Points of Valence Transition
Shinji Watanabe, Atsushi Tsuruta, Kazumasa Miyake +1
We study the mechanism how critical end points of first-order valence transitions are controlled by a magnetic field. We show that the critical temperature is suppressed to be a qu…
Theory of Ultrasonic Dispersion in Local Phonon Systems Coupled with Conduction Electrons
K. Hattori, K. Miyake
The physical origin of frequency dependence in elastic constants, which are often found in an ultrasound propagation in filled skutterudites and clathrate compounds, is investigate…
